553 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
554 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
555 create html formated docs. texi2html may not be ported to DOS.
556 (make.info, make.dvi, make.ps, make.html): Make targets depend on
558 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
559 -I switch to look in ./ instead of ./doc.
560 (html): Target depend on html-recursive instead of make_1.html.
561 (make_1.html): Removed.
562 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
563 (all-recursive): Allow for more than one subdir in the build
565 (mostlyclean-recursive, clean-recursive, distclean-recursive)
566 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
567 (tags-recursive): Allow for more than one subdir in the build
569 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
570 targets. Enter into doc/ to produce the targets.
571 (all-am): $(INFO_DEPS) replaced by info.
573 2009-09-26 Paul Smith <psmith@gnu.org>
575 * read.c (record_files): Use free_ns() to free struct nameseq.
578 * rule.c (freerule): Use free_dep_chain().
580 * read.c (record_files): Free FILENAMES chain for implicit rules.
581 (eval): Static pattern targets go into the string cache.
583 * function.c (string_glob): Free NAME in the nameseq chain.
585 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
587 * implicit.c (pattern_search): Terminate early if we haven't
588 found any rules to try (performance improvement).
590 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
592 * implicit.c (pattern_search): Merge three parallel arrays,
593 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
594 of struct TRYRULE. In the old version the latter two arrays
595 had insufficient length.
597 2009-09-24 Paul Smith <psmith@gnu.org>
599 * implicit.c (pattern_search): Add back support for order-only
600 prerequisites for secondary expansion implicit rules, that were
601 accidentally dropped. If we find a "|", enable order-only mode
602 and set IGNORE_MTIME on all deps that are seen afterward.
603 (pattern_search): Fix memory leaks: for intermediate files where
604 we've already set the file variable and pattern variable sets, be
605 sure to either save or free them as appropriate.
607 2009-09-23 Paul Smith <psmith@gnu.org>
609 Rework the way secondary expansion is stored, for efficiency.
610 This changes secondary expansion so that ONLY WHEN we know we have
611 a possibility of needing secondary expansion, do we defer the
612 secondary expansion. This means more parsing the deps but we use
613 a lot less memory (due to the strcache). Also, this fixes
616 * read.c (eval): Don't parse the dep string here anymore.
617 (record_files): Take the dep argument as an unparsed string. If
618 secondary expansion is enabled AND the prereq string has a '$' in
619 it, then set NEED_2ND_EXPANSION and keep the entire string.
620 Otherwise, parse the dep string here to construct the dep list
621 with the names in the strcache.
623 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
624 duplicate the name string (others are in the strcache).
626 * implicit.c: Remove struct idep and free_idep_chain(): unused.
627 (struct patdeps): New structure to store prereq information.
628 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
629 which prerequisites need expansion, and expand only those.
631 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
632 and enter_prereqs(). split_prereqs() takes a fully-expanded string
633 and splits it into a DEP list, handling order-only prereqs.
634 (enter_prereqs): This function enters a list of DEPs into the file
635 database. If there's a stem defined, expand any pattern chars.
636 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
637 set. Use the above functions.
638 (snap_deps): Only perform second expansion on prereqs that need it,
639 as defined by the NEED_2ND_EXPANSION flag.
640 (print_prereqs): New function to print the prereqs
641 (print_file): Call print_prereqs() rather than print inline.
643 * hash.h (STRING_COMPARE): Take advantage of strcache() by
645 (STRING_N_COMPARE): Ditto.
646 (ISTRING_COMPARE): Ditto.
648 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
649 (parse_file_seq): Return void*
650 * read.c (parse_file_seq): Return void*.
651 (eval): Invoke macroized version of parse_file_seq()
652 * default.c (set_default_suffixes): Ditto.
653 * file.c (split_prereqs): Ditto.
654 * function.c (string_glob): Ditto.
655 * main.c (main): Ditto.
656 * rule.c (install_pattern_rule): Ditto.
658 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
660 2009-09-16 Paul Smith <psmith@gnu.org>
662 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
664 * dep.h: Create alloc_dep() / free_dep() macros.
666 * implicit.c (pattern_search): Take advantage of the new
667 parse_file_seq() to add the directory prefix to each prereq.
669 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
670 all. Avoid reversing chains. Support adding prefixes.
671 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
672 cached/non-cached results.
673 (eval): Remove multi_glob() & invoke new parse_file_seq().
674 * rule.c (install_pattern_rule): Ditto.
675 * main.c (main): Ditto.
676 * implicit.c (pattern_search): Ditto.
677 * function.c (string_glob): Ditto.
678 * file.c (parse_prereqs): Ditto.
679 * default.c (set_default_suffixes): Ditto.
681 * variable.c (parse_variable_definition): Don't run off the end of
682 the string if it ends in whitespace (found with valgrind).
684 * commands.c (set_file_variables): Keep space for all targets in
685 $? if -B is given (found with valgrind).
687 2009-09-15 Paul Smith <psmith@gnu.org>
689 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
690 (xcalloc): Add new function.
691 * make.h: New declarations.
693 * ar.c (ar_glob_match): New calling method for concat().
694 * main.c (main): Ditto.
695 (decode_env_switches): Ditto.
696 * read.c (eval_makefile): Ditto.
697 (tilde_expand): Ditto.
698 (parse_file_seq): Ditto.
699 * variable.c (target_environment): Ditto.
700 (sync_Path_environment): Ditto.
702 * ar.c (ar_glob_match): Use xcalloc().
703 * dir.c (file_impossible): Ditto.
704 * file.c (enter_file): Ditto.
705 * job.c (new_job): Ditto.
706 * read.c (parse_file_seq): Ditto.
707 * vmsfunctions.c (opendir): Ditto.
709 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
711 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
712 inside the loop that looks up environment for PATH.
714 2009-08-31 Eli Zaretskii <eliz@gnu.org>
716 * function.c (windows32_openpipe): Update envp after calling
717 sync_Path_environment.
719 2009-08-02 Paul Smith <psmith@gnu.org>
721 * remake.c (notice_finished_file): Ensure file->cmds is not null
722 before looping through them. Fixes Savannah bug #21824.
724 * doc/make.texi (Wildcard Examples): Clarify when objects is
725 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
726 (Include): Clarify the behavior of -include.
727 Fixes Savannah bug #18963.
729 2009-08-01 Paul Smith <psmith@gnu.org>
731 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
732 etc. come on the command line. Fixes Savannah bug #27093.
734 * expand.c (expand_argument): If the argument is large enough use
735 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
737 * variable.c (do_variable_definition): Avoid using alloca() to
738 hold values, which can be large. Fixes Savannah bug #23960.
740 * job.c (new_job): Use memmove() instead of strcpy() since both
741 pointers are in the same memory block. Fixes Savannah bug #27148.
742 Patch by Petr Machata.
744 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
746 * job.c (construct_command_argv_internal): Add "ulimit" and
747 "unset" to the sh_cmds for Unixy shells.
749 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
751 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
752 that set make_cv_sys_gnu_glob, so they are also correctly set
753 when the cache has been populated before.
755 2009-07-04 Eli Zaretskii <eliz@gnu.org>
757 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
758 exist, as realpath(3) does where it's supported.
760 2006-07-04 Eli Zaretskii <eliz@gnu.org>
762 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
763 (abspath): Support systems that define HAVE_DOS_PATHS (have
764 drive letters in their file names). Use IS_PATHSEP instead of a
765 literal '/' comparison. Fixes Savannah bug #26886.
767 2009-06-14 Paul Smith <psmith@gnu.org>
769 * remake.c (update_file_1): Remember the original file we marked
770 as updating, so we can clear that flag again. If we find a target
771 via vpath, FILE might change.
772 (check_dep): Ditto. Fixes Savannah bug #13529.
773 Patch by Reid Madsen <reid.madsen@tek.com>.
775 2009-06-13 Paul Smith <psmith@gnu.org>
777 * doc/make.texi (MAKEFILES Variable): Be explicit that files
778 included by MAKEFILES cannot give default goals.
779 * read.c (eval): If set_default is not set, pass the no-default-goal
780 value when we read included makefiles. Fixes Savannah bug #13401.
782 * ar.c (ar_name): Ensure that targets with empty parens aren't
783 considered archive member references: archive members must have a
784 non-empty "member" string. Fixes Savannah bug #18435.
786 * function.c (string_glob): Rely on multi_glob() to determine
787 whether files exist or not. Remove call to file_exists_p() which
788 is not always correct. Fixes Savannah bug #21231.
789 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
790 then only files that really exist will be returned.
791 * dep.h: Add new argument to multi_glob().
792 * rule.c (install_pattern_rule): Ditto.
793 * read.c (eval): Ditto.
794 * main.c (main): Ditto.
795 * implicit.c (pattern_search): Ditto.
796 * file.c (parse_prereqs): Ditto.
797 * default.c (set_default_suffixes): Ditto.
799 2009-06-09 Paul Smith <psmith@gnu.org>
801 * commands.c (set_file_variables): If always_make_flag is set,
802 always add the prereq to $?. Fixes Savannah bug #17825.
804 * remake.c (update_file_1): When rebuilding deps of FILE, also try
805 to rebuild the deps of all the also_make targets for that file.
806 Fixes Savannah bug #19108.
808 * implicit.c (pattern_search): Undo test for is_target, added by
809 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
810 Rule Search Algorithm". Fixes Savannah bug #17752.
812 * main.c (clean_jobserver): Clear the jobserver_fds options and
813 set job_slots to the default when we clean up.
814 (define_makeflags): Return the new MAKEFLAGS value.
815 (main): Reset MAKEFLAGS in the environment when we re-exec.
816 Fixes Savannah bug #18124.
818 2009-06-08 Paul Smith <psmith@gnu.org>
820 * read.c (eval): Collapse continuations post-semicolon on target-
821 specific variables. Fixes Savannah bug #17521.
823 2009-06-07 Paul Smith <psmith@gnu.org>
825 * job.c (reap_children): For older systems without waitpid() (are
826 there any of these left?) run wait(2) inside EINTRLOOP to handle
827 EINTR errors. Fixes Savannah bug #16401.
829 * (various): Debug message cleanup. Fixes Savannah bug #16469.
831 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
833 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
834 not the end, to catch second expansion $(eval ...) defining new
835 target/prereq relationships during snap_deps.
836 Fixes Savannah bug #24622.
838 * read.c (record_files): The second-expansion "f->updating" hack
839 was not completely correct: if assumed that the target with
840 commands always had prerequisites; if one didn't then the ordering
841 was messed up. Fixed for now to use f->updating to decide whether
842 to preserve the last element in the deps list... but this whole
843 area of constructing and reversing the deps list is too confusing
844 and needs to be reworked. Fixes Savannah bug #21198.
846 2009-06-06 Paul Smith <psmith@gnu.org>
848 * hash.c (hash_insert): Remove useless test for NULL.
849 Fixes Savannah bug #21823.
851 * make.h: Move SET_STACK_SIZE determination to make.h.
852 * main.c (main): New global variable, STACK_LIMIT, holds the
853 original stack limit when make was started.
854 * job.c (start_job_command): Reset the stack limit, if we changed it.
855 Fixes Savannah bug #22010.
857 * remake.c (check_dep): Only set the target's state to not-started
858 if it's not already running. Found this while testing -j10 builds
859 of glibc: various targets were being rebuilt multiple times.
860 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
863 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
864 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
867 2009-06-04 Paul Smith <psmith@gnu.org>
869 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
871 * maintMakefile: Modify access of config and gnulib Savannah
872 modules to use GIT instead of CVS.
874 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
875 Fixes Savannah bug #24655.
877 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
878 this can happen during some invocations of $(eval ...) for example.
879 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
881 2009-06-02 Paul Smith <psmith@gnu.org>
883 * configure.in: Check for fileno()
884 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
885 for the makefile file so invocations of $(shell ...) don't inherit it.
886 Fixes Savannah bug #24277.
888 2009-06-01 Paul Smith <psmith@gnu.org>
890 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
891 expansion was handled incorrectly. Rework the default goal
892 handling to save the variable only. Remove default_goal_file and
894 * read.c (eval): Check default_goal_var, not default_goal_name.
895 * read.c (record_target_var): Don't check default_goal_file here.
897 2009-05-31 Paul Smith <psmith@gnu.org>
899 * main.c (main): Expand the .DEFAULT_GOAL variable before using
900 it, and if the multi_glob() returns nothing (say it expanded to
901 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
903 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
904 $(and ..) to the reference. Fixes Savannah bug #25694.
906 * make.1: Be clear that some recipes will be executed even with -n.
907 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
909 * doc/make.texi (Override Directive): Make more clear how
910 overrides and appends interact.
911 Elucidates part of Savannah bug #26207.
913 * read.c (record_target_var): Don't reset the origin on
914 target-specific variables; try_variable_definition() will handle
915 this correctly. Fixes Savannah bug #26207.
917 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
918 Fixes Savannah bug #25712.
920 * implicit.c (pattern_search): Keep a pointer to the beginning of
921 the filename and save that instead of the constructed pointer.
922 Fixes Savannah bug #26593.
923 Patch by Mark Seaborn <mrs@mythic-beasts.com>
925 2009-05-30 Paul Smith <psmith@gnu.org>
927 * doc/make.texi (Multi-Line): Add a description of the new abilities
928 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
929 "command sequence" vs. "recipe" syntax.
930 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
931 after a define, to create variables with those flavors.
933 2009-05-25 Paul Smith <psmith@gnu.org>
935 Reworked the parser for variable assignments to allow multiple
936 modifiers, and in any order. Also allows variable and
937 prerequisites to be modifier names ('export', 'private', etc.)
939 * NEWS: Add notes about user-visible changes.
941 * read.c (struct vmodifiers): Remember what modifiers were seen.
942 (parse_var_assignment): New function to parse variable assignments.
943 (eval): Call the new function. Handle variable assignments earlier.
945 * variable.c (parse_variable_definition): Only parse; don't create var.
946 (assign_variable_definition): Call parse, then create the var.
948 2009-05-24 Paul Smith <psmith@gnu.org>
950 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
951 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
953 2009-03-14 Eli Zaretskii <eliz@gnu.org>
955 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
956 Fixes Savannah bug #25412.
958 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
959 prototype for xmalloc.
960 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
961 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
962 Loop over an array of extensions, instead of duplicating the same
963 code inline. Use SearchPath followed by CreateFile, instead of
964 the obsolete OpenFile. Fixes Savannah bug #17277.
965 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
966 to `find_file'. Fixes Savannah bug #25662.
968 2009-03-07 Eli Zaretskii <eliz@gnu.org>
970 * function.c (func_shell): Don't close pipedes[1] if it is -1.
971 Fixes Savannah bug #20495.
973 2009-02-28 Ralf Wildenhues <address@hidden>
975 * doc/make.texi (Instead of Execution): Document interaction of
976 -t with phony targets.
978 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
980 Introduce a new keyword "private" which applies to target-specific
981 variables and prevents their values from being inherited.
983 * variable.h (struct variable): Add private_var flag to each variable.
984 Add a flag to specify which list entry switches to the parent target.
985 * variable.c (define_variable_in_set): Initialize private_var flag.

1004 2008-09-30 Eli Zaretskii <eliz@gnu.org>
1006 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
1009 * w32/subproc/build.bat (GCCBuild): Likewise.
1011 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
1013 * job.c (construct_command_argv_internal): Avoid extra backslash
1014 in batch-mode Unixy shells. Under DB_JOBS, display the contents
1017 2008-05-31 Eli Zaretskii <eliz@gnu.org>
1019 * README.W32.template: Remove obsolete text about non-support for
1020 -jN without Unixy shell. Remove obsolete text about not supplying
1021 Visual Studio project files (we do supply them). Modify text to
1022 prefer GCC builds to MSC builds.
1024 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1026 * doc/make.texi (Empty Targets): Fix typo.
1028 2008-03-27 Paul Smith <psmith@gnu.org>
1030 Fix Savannah bug #22379:
1031 * ar.c (ar_glob_match): Zero the allocated structure.
1032 * read.c (parse_file_seq): Ditto.
1034 2008-03-08 Brian Dessent <brian@dessent.net>

1038 2008-01-26 Eli Zaretskii <eliz@gnu.org>
1040 * variable.c (target_environment): Don't use shell_var if its
1041 `value' field is NULL.
1043 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1045 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
1047 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
1048 (TEXINFOS): Value changed to `doc/make.texi'.
1049 (.SUFFIXES): Use .texi instead of .texinfo.
1050 (make.info, make.dvi): Depend on doc/make.texi.
1051 (.texi.info): New target, instead of ".texinfo.info". Change -I
1052 switch to $(MAKEINFO) to look in doc/. Use --no-split.
1053 (.texi): New target, instead of ".texinfo". Change -I switch to
1054 $(MAKEINFO) to look in doc/. Use --no-split.
1055 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
1056 switch to $(MAKEINFO) to look in doc/.
1057 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
1058 "*.i[0-9][0-9]" (due to --no-split above).
1059 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
1060 (html, make_1.html): New targets.
1061 (.PHONY): Add "html".
1062 (.SUFFIXES): Add .html.
1064 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
1066 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
1067 HAVE_DECL_SYS_SIGLIST.
1069 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1070 build does not use child_execute_job.
1072 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1073 export the SHELL environment variable to the child.

1084 2007-11-04 Paul Smith <psmith@gnu.org>
1086 * doc/make.texi: Convert references to "commands", "command
1087 lines", and "command script" to "recipe".

1097 2007-10-12 Eli Zaretskii <eliz@gnu.org>
1099 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1100 a more complex value than a simple shell: if it's not a default
1101 shell now then expand it and see if is a default shell then.
1103 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1105 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1106 pathnames, with const strings.
1107 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one

1112 * make.h: Add a prototype for w32_kill() (change suggested by

1127 2007-09-11 Paul Smith <psmith@gnu.org>
1129 * doc/make.texi (Special Variables): Moved this into the "How to
1130 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.

1134 (Simple Makefile): Ditto.
1135 (Rule Syntax): Ditto.
1136 (Command Syntax): Ditto.
1137 (Error Messages): Ditto.
1139 2007-09-10 Paul Smith <psmith@gnu.org>
1141 * commands.c (print_commands): Don't print an extra line in the
1142 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1144 * read.c (construct_include_path): Add the full string to the cache; we
1145 were chopping the last char.
1147 * NEWS: Announce the .RECIPEPREFIX special variable.
1148 * variable.c (lookup_special_var): Rename from handle_special_var().
1149 (lookup_variable): Call the new name.
1150 (set_special_var): New function: handle setting of special variables.
1151 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.

1154 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1155 * main.c (main): Create the .RECIPEPREFIX special variable.
1156 * read.c (eval): Remove the cmd_prefix characters from the command
1157 scripts here, so they're not stored in the commands array at all,
1158 rather than waiting and stripping them out during command construction.
1159 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1161 2007-08-15 Paul Smith <psmith@gnu.org>
1163 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1164 file has had the section info removed, so add some to make.texi
1165 before we include it.
1167 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1169 * remake.c (check_dep): Reset the target state for intermediate
1170 files. They might have been considered before but not updated

1185 2007-07-13 Paul Smith <psmith@gnu.org>
1187 * file.c (expand_deps): Use variable_buffer as the start of the
1188 buffer, not the original pointer (in case it was reallocated).
1189 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1190 Fixes Savannah bug #20452.

1220 Add support for Objective C. Fixes Savannah bug #16389.
1221 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.

1227 Dave Korn <dave.korn@artimi.com>
1229 2007-05-08 Paul Smith <psmith@gnu.org>
1231 Fix Savannah bug #19656:
1233 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1235 * make.h: Change all case-insensitive string compares to use
1236 strcasecmp() (from POSIX). If we don't have that but do have one
1237 of the others, define strcasecmp to be one of those instead. If
1238 we don't have any, declare a prototype for our own version.
1240 * misc.c (strcasecmp): Use this if we can't find any native
1241 case-insensitive string comparison function.
1242 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1243 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1245 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1246 strcasecmp() instead of stricmp().
1247 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1248 instead of strcmpi().
1249 * acinclude.m4: Remove the strcasecmp() check from here.
1251 2007-03-21 Paul Smith <psmith@gnu.org>
1253 * configure.in: Don't turn on case-insensitive file system support
1254 if --disable-... is given. Fixes Savannah bug #19348.
1256 2007-03-19 Paul Smith <psmith@gnu.org>
1258 * ALL: Use the strcache for all file name strings, or other
1259 strings which we will never free. The goal is to save memory by
1260 avoiding duplicate copies of strings. However, at the moment this
1261 doesn't save much memory in most situations: due to secondary
1262 expansion we actually save prerequisite lists twice (once before
1263 the secondary expansion, and then again after it's been parsed
1264 into individual file names in the dep list). We will resolve this
1265 in a future change, by doing the parsing up-front for targets
1266 where secondary expansion is not set.
1268 Moving things into the strcache also allows us to use const
1269 pointers in many more places.
1271 2007-01-03 Paul Smith <psmith@gnu.org>
1273 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1274 the function, not just the first. Fixes Savannah bug #18680.
1276 2006-11-18 Paul Smith <psmith@gnu.org>
1278 * strcache.c (strcache_add_len): Don't allocate a new buffer
1279 unless the string is not already nil-terminated. Technically this
1280 is a violation of the standard, since we may be passed an array
1281 that is not long enough to test one past. However, in make this
1282 is never true since we only use nil-terminated strings or
1283 sub-strings thereof.
1285 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1287 * main.c: New global cmd_prefix, defaults to '\t'.
1288 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1291 * dir.c: Constified.
1292 (dir_contents_file_exists_p): Check for an error return from
1293 readdir(), just in case.
1295 * commands.c: Constified.
1296 * default.c: Constified.
1297 * expand.c: Constified.
1298 * function.c: Partial constification.

1302 * vpath.c: Partial constification.
1303 * w32/pathstuff.c: Partial constification.
1305 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1307 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1308 backslashes and drive letters as absolute.
1310 2006-10-22 Paul Smith <psmith@gnu.org>
1312 * main.c (struct command_switch): Use const and void*.
1314 2006-10-21 Paul Smith <psmith@gnu.org>
1317 * arscan.c: Constified.
1319 2006-09-30 Paul Smith <psmith@gnu.org>
1321 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1322 point to lastword since the example was updated.
1323 Fixes Savannah bug #16304.
1324 (Secondary Expansion): Correct example description.
1325 Fixes Savannah bug #16468.
1326 (Makefile Contents): Clarify that comments cannot appear within
1327 variable references or function calls.
1328 Fixes Savannah bug #16577.
1329 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1330 Fixes Savannah bug #17701.
1331 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:

1333 prerequisites. Fixes Savannah bug #17880.
1334 (Rule Syntax): "lise" -> "list"
1335 (Multiple Rules): ... -> @dots{}
1336 (Splitting Lines): ditto.
1338 * remake.c (update_file_1): Prereqs that don't exist should be
1339 considered changed, for the purposes of $?.
1340 Fixes Savannah bug #16051.
1342 * make.1: Remove extraneous "+".
1343 Fixes Savannah bug #16652.

1360 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]: Define
1361 sh_chars_sh for Windows platforms that emulate Unix.

1379 2006-04-20 Paul D. Smith <psmith@gnu.org>
1381 * maintMakefile (po-check): Use Perl instead of grep -E, for systems
1382 that don't have extended grep.
1383 (cvsclean): Use $(PERL) instead of perl.
1385 2006-04-09 Paul D. Smith <psmith@gnu.org>
1387 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
1389 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1390 inner-scope variables don't mask outer-scope variables.
1392 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:
1393 * function.c, getloadavg.c, implicit.c, job.c, main.c, misc.c, read.c:

1395 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
1396 values from memory allocation functions: they return void* and so
1397 don't need to be cast. Also remove (char *) casts of arguments to

1412 2006-04-06 Paul D. Smith <psmith@gnu.org>
1414 * configure.in: Removed AM_C_PROTOTYPES. Starting now on we
1415 require an ISO C 1989 standard compiler and runtime library.

1451 Declare and define sh_chars_sh[].
1453 2006-03-23 Paul D. Smith <psmith@gnu.org>
1455 * configure.in: Look for build.sh.in in $srcdir so it will be
1456 built for remote configurations as well.
1458 * Makefile.am: Make sure to clean up build.sh during distclean.
1459 Fixes Savannah bug #16166.
1461 * misc.c (log_access): Takes a const char *.

1473 * remake.c (update_file): Add alloca(0) to clean up alloca'd
1474 memory on hosts that don't support it directly.

1477 make sure I don't forget any).
1479 * main.c (clean_jobserver): Move jobserver cleanup code into a new
1481 (die): Cleanup code was removed from here; call the new function.
1482 (main): If we are re-execing, clean up the jobserver first so we
1483 don't leak file descriptors.

1496 (copy_dep_chain): Copy stem.
1497 (free_dep_chain): Use free_dep.
1498 * read.c (record_files): Store stem in the dependency line.

1512 (allocated_variable_append): Don't expand the final result.
1513 Fixes Savannah bug #15913.
1515 2006-03-09 Paul Smith <psmith@gnu.org>
1517 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1518 listed non-existent files as changed. Turns out there's a bug in
1519 the Linux kernel builds which means that this change causes
1520 everything to rebuild every time. We will re-introduce this fix
1521 in the next release, to give them time to fix their build system.
1522 Fixes Savannah bug #16002.
1523 Introduces Savannah bug #16051.

1542 * commands.c (set_file_variables): Realloc, not malloc, the static
1543 string values to avoid memory leaks.
1545 * expand.c (recursively_expand_for_file): Only set reading_file to
1546 an initialized value.
1548 * implicit.c (pattern_search): We need to make a copy of the stem
1549 if we get it from an intermediate dep, since those get freed.
1551 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1553 (enter_file) [VMS]: Ditto.

1558 * job.c (construct_command_argv_internal): Fix last change.
1560 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1561 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1562 the calls to _beginthreadex.
1564 * expand.c (recursively_expand_for_file): Initialize `save' to
1565 prevent compiler warnings.
1567 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1569 * job.c (construct_command_argv_internal): Don't create a temporary

1571 script file stream to text mode.

1575 * variable.c (merge_variable_set_lists): Don't try to merge the
1576 global_setlist. Not only is this useless, but it can lead to
1577 circularities in the linked list, if global_setlist->next in one
1578 list gets set to point to another list which also ends in

1582 2006-02-15 Paul D. Smith <psmith@gnu.org>
1584 Fix for Savannah bug #106.
1586 * expand.c (expanding_var): Keep track of which variable we're
1587 expanding. If no variable is being expanded, it's the same as
1589 * make.h (expanding_var): Declare it.
1590 * expand.c (recursively_expand_for_file): Set expanding_var to the
1591 current variable we're expanding, unless there's no file info in
1592 it (could happen if it comes from the command line or a default
1593 variable). Restore it before we exit.

1598 (func_wordlist): Ditto.
1599 (func_error): Ditto.
1600 (expand_builtin_function): Ditto.
1601 (handle_function): Ditto.
1603 2006-02-14 Paul D. Smith <psmith@gnu.org>
1605 * read.c (eval): Even if the included filenames expands to the
1606 empty string we still need to free the allocated buffer.
1608 * implicit.c (pattern_search): If we allocated a variable set for
1609 an impossible file, free it.
1610 * variable.c (free_variable_set): New function.
1611 * variable.h: Declare it.
1613 * read.c (read_all_makefiles): Makefile names are kept in the
1614 strcache, so there's never any need to alloc/free them.
1617 * main.c (main): Add "archives" to the .FEATURES variable if
1618 archive support is enabled.
1619 * doc/make.texi (Special Variables): Document it.

1629 * (ALL FILES): Updated copyright and license notices.
1631 2006-02-10 Paul D. Smith <psmith@gnu.org>
1633 A new internal capability: the string cache is a read-only cache
1634 of strings, with a hash table interface for fast lookup. Nothing
1635 in the cache will ever be freed, so there's no need for reference
1636 counting, etc. This is the beginning of a full solution for
1637 Savannah bug #15182, but for now we only store makefile names here.
1639 * strcache.c: New file. Implement a read-only string cache.
1640 * make.h: Add prototypes for new functions.
1641 * main.c (initialize_global_hash_tables): Initialize the string cache.
1642 (print_data_base): Print string cache stats.
1643 * read.c (eval_makefile): Use the string cache to store makefile
1644 names. Rewrite the string allocation to be sure we free everything.

1652 2006-02-09 Paul D. Smith <psmith@gnu.org>
1654 * function.c (func_or): Implement a short-circuiting OR function.
1655 (func_and): Implement a short-circuiting AND function.
1656 (function_table_init): Update the table with the new functions.
1657 * doc/make.texi (Conditional Functions): Changed the "if" section
1658 to one on general conditional functions. Added documentation for
1659 $(and ...) and $(or ...) functions.
1660 * NEWS: Note new $(and ...) and $(or ...) functions.
1662 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
1664 * job.h (struct child): Add the dontcare bitfield.
1665 * job.c (new_job): Cache dontcare flag.
1666 * job.c (reap_children): Use cached dontcare flag instead of the
1667 one in struct file. Fixes Savannah bug #15641.
1669 2006-02-06 Paul D. Smith <psmith@gnu.org>
1671 * vpath.c (selective_vpath_search): If the file we find has a
1672 timestamp from -o or -W, use that instead of the real time.
1673 * remake.c (f_mtime): If the mtime is a special token from -o or
1674 -W, don't overwrite it with the real mtime.
1675 Fixes Savannah bug #15341.
1677 Updates from Markus Mauhart <qwe123@chello.at>:
1679 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.

1691 to avoid walking the list every time we want to add a new one.
1692 Fixes Savannah bug #15533.
1693 * filedef.h (struct file): Add a new LAST pointer.
1695 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1696 the comparison. For 64-bits systems the result of the subtraction
1697 might not fit into an int. Use comparison instead.
1698 Fixes Savannah bug #15534.
1700 * doc/make.texi: Update the chapter on writing commands to reflect
1701 the changes made in 3.81 for backslash/newline and SHELL handling.

1721 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1723 * remake.c (update_goal_chain): Set g->changed instead of
1724 incrementing it, as it is only 8-bit wide, and could overflow if
1725 many commands got started in update_file.
1727 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1729 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1730 MAXIMUM_WAIT_OBJECTS.

1734 (process_register): Don't register more processes than the
1735 available number of slots.
1736 (process_easy): Don't start new processes if all slots are used up.
1738 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
1739 are already more children than sub_proc.c can handle, behave as if
1740 the load were too high.
1741 (start_job_command): Fix a typo in error message when process_easy
1744 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1746 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1747 the shell is not sh.exe.
1749 * job.c (create_batch_file): Renamed from create_batch_filename;
1750 all callers changed. Don't close the temporary file; return its
1751 file descriptor instead. New arg FD allows to return the file
1753 (construct_command_argv_internal): Use _fdopen instead of fopen to
1754 open the batch file.
1756 2006-01-04 Paul D. Smith <psmith@gnu.org>
1758 * readme.vms: Updates for case-insensitive VMS file systems from

1779 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
1780 disable warnings for MSC.
1781 Patch by Rob Tulloh <rtulloh@yahoo.com>.
1783 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1785 * doc/make.texi (Execution): Add a footnote about changes in
1786 handling of backslash-newline sequences. Mention the differences
1787 on MS-DOS and MS-Windows.
1789 * NEWS: More details about building the MinGW port and a pointer
1790 to README.W32. Fix the section name that describes the new
1791 backward-incompatible processing of backslash-newline sequences.
1792 The special processing of SHELL set to "cmd" is only relevant to
1793 MS-Windows, not MS-DOS.
1795 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1797 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1798 to DWORD, to avoid compiler warnings.
1799 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1800 use %ld in format, to avoid compiler warnings.
1802 * doc/make.texi (Special Targets): Fix a typo.
1803 (Appending): Fix cross-reference to Setting.
1804 (Special Variables, Secondary Expansion, File Name Functions)
1805 (Flavor Function, Pattern Match, Quick Reference): Ensure two

1814 * read.c (record_target_var): Initialize variable's export field
1815 with v_default instead of leaving it "initialized" by whatever
1816 garbage happened to be on the heap.
1818 2005-12-12 Paul D. Smith <psmith@gnu.org>
1820 * make.1: Fix some display errors and document all existing options.
1821 Patch by Mike Frysinger <vapier@gentoo.org>.
1823 2005-12-11 Paul D. Smith <psmith@gnu.org>
1825 * implicit.c (pattern_search): If 2nd expansion is not set for
1826 this implicit rule, replace the pattern with the stem directly,
1827 and don't re-expand the variable list. Along with the other
1828 .SECONDEXPANSION changes below, fixes bug #13781.
1830 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1832 * implicit.c (pattern_search): Mark other files that this rule
1833 builds as targets so that they are not treated as intermediates
1834 by the pattern rule search algorithm. Fixes bug #13022.
1836 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1838 * remake.c (notice_finished_file): Propagate the change of
1839 modification time to all the double-colon entries only if

1858 * read.c (record_files): Don't set deps flags if there are no deps.
1859 * maintMakefile: We only need to build the templates when we are
1860 creating a distribution, so don't do it for "all".
1862 2005-10-24 Paul D. Smith <psmith@gnu.org>
1864 Make secondary expansion optional: its enabled by declaring the
1865 special target .SECONDEXPANSION.
1867 * NEWS: Update information on second expansion capabilities.
1868 * doc/make.texi (Secondary Expansion): Document the
1869 .SECONDEXPANSION special target and its behavior.

1871 prerequisite list was found in a static pattern rule.
1872 (free_dep_chain): Declare a prototype.
1873 * file.c (parse_prereqs): New function: break out some complexity
1875 (expand_deps): If we aren't doing second expansion, replace % with
1876 the stem for static pattern rules. Call the new function.
1877 * filedef.h (parse_prereqs): Declare a prototype.
1878 * implicit.c (pattern_search): Initialize the new staticpattern
1880 * main.c (second_expansion): Declare a global variable to remember
1881 if the special target has been seen. Initialize the new
1882 staticpattern field for prerequisites.
1883 * make.h: Extern for second_expansion.
1884 * misc.c (free_dep_chain): New function: frees a struct dep list.
1885 * read.c (read_all_makefiles): Initialize the staticpattern field.
1886 (eval_makefile): Ditto.
1887 (record_files): Check for the .SECONDEXPANSION target and set
1888 second_expansion global if it's found.
1889 Use the new free_dep_chain() instead of doing it by hand.
1890 Set the staticpattern field for prereqs of static pattern targets.
1892 2005-10-16 Paul D. Smith <psmith@gnu.org>
1894 * main.c (main): Set CURDIR to be a file variable instead of a
1895 default, so that values of CURDIR inherited from the environment
1896 won't override the make value.
1898 2005-09-26 Paul D. Smith <psmith@gnu.org>
1900 * job.c (construct_command_argv_internal): If the line is empty
1901 remember to free the temporary argv strings.
1904 2005-09-16 Paul D. Smith <psmith@gnu.org>
1906 * job.c (start_job_command): The noerror flag is a boolean (single
1907 bit); set it appropriately.
1908 Reported by Mark Eichin <eichin@metacarta.com>
1910 2005-08-29 Paul D. Smith <psmith@gnu.org>
1912 * function.c (func_error): On Windows, output from $(info ...)
1913 seems to come in the wrong order. Try to force it with fflush().
1915 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1917 * read.c (record_files): Move code that sets stem for static
1918 pattern rules out of the if (!two_colon) condition so it is
1919 also executed for two-colon rules. Fixes Savannah bug #13881.
1921 2005-08-08 Paul D. Smith <psmith@gnu.org>
1923 * make.h: Don't test that __STDC__ is non-0. Some compilers
1924 (Windows for example) set it to 0 to denote "ISO C + extensions".
1927 2005-08-07 Paul D. Smith <psmith@gnu.org>
1929 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1930 conditional (slightly different version of a fix from Eli).
1932 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1933 If make is running in parallel without -k and two jobs die in a
1934 row, but not too close to each other, then make will quit without
1935 waiting for the rest of the jobs to die.
1937 * main.c (die): Don't reset err before calling reap_children() the
1938 second time: we still want it to be in the error condition.
1939 * job.c (reap_children): Use a static variable, rather than err,
1940 to control whether or not the error message should be printed.
1942 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1944 * w32/subproc/sub_proc.c: Include signal.h.
1945 (process_pipe_io, process_file_io): Pass a pointer to a local
1946 DWORD variable to GetExitCodeProcess. If the exit code is
1947 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1949 * job.c [WINDOWS32]: Include windows.h.
1950 (main_thread) [WINDOWS32]: New global variable.
1951 (reap_children) [WINDOWS32]: Get the handle for the main thread
1952 and store it in main_thread.
1954 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1955 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1956 doing anything else. When we are done, close the main thread
1957 handle and exit with status 130.
1959 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1961 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1964 * main.c (find_and_set_default_shell): If found a DOSish shell,
1965 set sh_found and the value of default_shell, and report the
1966 findings in debug mode.
1968 * job.c (construct_command_argv_internal): Check unixy_shell, not
1969 no_default_sh_exe, to decide whether to use Unixy or DOSish
1972 * README.W32: Update with info about the MinGW build.
1974 * build_w32.bat: Support MinGW.
1976 * w32/subproc/build.bat: Likewise.
1978 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
1979 printing DWORD args.
1981 * function.c (windows32_openpipe): Fix format strings for printing
1984 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
1986 (start_job_command): Fix format string for printing the result of
1988 (start_job_command) [WINDOWS32]: Do not define.
1989 (exec_command): Fix format string for printing HANDLE args.
1991 * main.c (handle_runtime_exceptions): Fix sprintf format strings
1992 to avoid compiler warnings.
1993 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
1994 (Note: some of these fixes were submitted independently by J. Grant)

1998 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
1999 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
2000 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
2002 2005-07-15 Paul Smith <psmith@gnu.org>
2004 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
2005 we don't have a POSIX shell, then revert to the old
2006 backslash-newline behavior (where they are stripped).
2009 2005-07-08 Paul D. Smith <psmith@gnu.org>
2011 * config.h.W32.template: Reorder to match the standard config.h,
2012 for easier comparisons.
2013 From J. Grant <jg@jguk.org>
2015 * maintMakefile: Remove .dep_segment before overwriting it, in
2016 case it's not writable or noclobber is set.
2017 * expand.c (variable_expand_string): Cast result of pointer
2018 arithmetic to avoid a warning.
2019 * main.c (switches): Add full-fledged final initializer.
2021 2005-07-06 Paul D. Smith <psmith@gnu.org>
2023 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2024 * signame.c (strsignal): If we found _sys_siglist[] or
2025 __sys_siglist[] use those instead of sys_siglist[].
2026 From Albert Chin <china@thewrittenword.com>
2028 2005-07-04 Paul D. Smith <psmith@gnu.org>
2030 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
2031 globfree(); set up to use the GNU versions.
2032 From Martin Zinser <zinser@zinser.no-ip.info>
2034 2005-07-03 Paul D. Smith <psmith@gnu.org>
2036 From J. Grant <jg@jguk.org>:

2044 2005-06-28 Paul D. Smith <psmith@gnu.org>
2046 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2047 declaration was checked but not present.
2049 2005-06-27 Paul D. Smith <psmith@gnu.org>
2051 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2052 to unsigned long. Fixes Savannah bug #13550.
2054 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2055 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
2056 Fixes Savannah bug #13551.
2058 2005-06-26 Paul D. Smith <psmith@gnu.org>
2060 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2061 it if ANSI_STRING is not set.
2063 2005-06-25 Paul D. Smith <psmith@gnu.org>
2065 * read.c (eval): If no filenames are passed to any of the
2066 "include" variants, don't print an error.
2067 * doc/make.texi (Include): Document this.
2068 Fixes Savannah bug #1761.
2070 * job.c (construct_command_argv_internal): Sanitize handling of
2071 backslash/newline pairs according to POSIX: that is, keep the
2072 backslash-newline in the command script, but remove a following
2073 TAB character, if present. In the fast path, make sure that the
2074 behavior matches what the shell would do both inside and outside
2075 of quotes. In the slow path, quote the backslash and put a
2076 literal newline in the string.
2077 Fixes Savannah bug #1332.
2078 * doc/make.texi (Execution): Document the new behavior and give
2080 * NEWS: Make a note of the new behavior.
2082 * make.h [WINDOWS32]: #include <direct.h>.
2083 Fixes Savannah bug #13478.
2085 * remake.c (name_mtime): If the stat() of a file fails and the -L
2086 option was given and the file is a symlink, take the best mtime of
2087 the symlink we can get as the mtime of the file and don't fail.
2088 Fixes Savannah bug #13280.
2090 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2091 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2092 inside a variable reference. Make this function static as it's
2094 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2095 parsing an unexpanded line looking for semicolons.
2096 Fixes Savannah bug #1454.
2097 * misc.c (remove_comments): Move this to read.c and make it static
2098 as it's only used there. Call find_char_unquote() with new arg.
2099 * make.h: Remove prototypes for find_char_unquote() and
2100 remove_comments() since they're static now.
2102 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2103 its export flag and obtain its value. When we need to re-exec,
2104 increment the value and add it into the environment.
2105 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2106 * NEWS: Mention MAKE_RESTARTS.
2107 * main.c (always_make_set): New variable. Change the -B option to
2108 set this one instead.
2109 (main): When checking makefiles, only set always_make_flag if
2110 always_make_set is set AND the restarts flag is 0. When building
2111 normal targets, set it IFF always_make_set is set.
2112 (main): Avoid infinite recursion with -W, too: only set what-if
2113 files to NEW before we check makefiles if we've never restarted
2114 before. If we have restarted, set what-if files to NEW _after_ we
2116 Fixes Savannah bug #7566:
2118 2005-06-17 Paul D. Smith <psmith@gnu.org>
2120 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2121 in the prerequisites list.
2123 2005-06-12 Paul D. Smith <psmith@gnu.org>
2125 Fix Savannah bug # 1328.
2127 * configure.in: Check for atexit().
2128 * misc.c (close_stdout): Test stdout to see if writes to it have
2129 failed. If so, be sure to exit with a non-0 error code. Based on
2130 code found in gnulib.
2131 * make.h: Prototype.
2132 * main.c (main): Install close_stdout() with atexit().
2134 2005-06-10 Paul D. Smith <psmith@gnu.org>
2136 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2138 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2139 headers; make vmsWaitForChildren() static; extern vmsify().
2140 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2141 Don't create child_execute_job() here (it's in vmsjobs.c).
2142 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2144 2005-06-09 Paul D. Smith <psmith@gnu.org>
2146 * variable.c (push_new_variable_scope): File variables point
2147 directly to the global_setlist variable. So, inserting a new
2148 scope in front of that has no effect on those variables: they
2149 don't go through current_variable_set_list. If we're pushing a
2150 scope and the current scope is global, push it "the other way" so
2151 that the new setlist is in the global_setlist variable, and
2152 next points to a new setlist with the global variable set.
2153 (pop_variable_scope): Properly undo a push with the new
2155 Fixes Savannah bug #11913.
2157 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2159 * job.c (reap_children): Don't die of the command failed but
2160 the dontcare flag is set. Fixes Savannah bug #13216.
2162 * implicit.c (pattern_search): When creating a target from
2163 an implicit rule match, lookup pattern target and set precious
2164 flag in a newly created target. Fixes Savannah bug #13218.
2166 2005-05-13 Paul D. Smith <psmith@gnu.org>
2168 Implement "if... else if... endif" syntax.
2170 * read.c (eval): Push all checks for conditional words ("ifeq",
2171 "else", etc.) down into the conditional_line() function.
2172 (conditional_line): Rework to allow "else if..." clause. New
2173 return value -2 for lines which are not conditionals. The
2174 ignoring flag can now also be 2, which means "already parsed a
2175 true branch". If that value is seen no other branch of this
2176 conditional can be considered true. In the else parsing if there
2177 is extra text after the else, invoke conditional_line()
2178 recursively to see if it's another conditional. If not, it's an
2179 error. If so, raise the conditional value to this level instead
2180 of creating a new conditional nesting level. Special check for
2181 "else" and "endif", which aren't allowed on the "else" line.
2182 * doc/make.texi (Conditional Syntax): Document the new syntax.
2184 2005-05-09 Paul D. Smith <psmith@gnu.org>
2186 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2187 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2188 recurses to the w32 directory, even on non-Windows systems. Use
2189 the method suggested in the automake manual.
2190 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2191 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2193 2005-05-07 Paul D. Smith <psmith@gnu.org>
2195 * main.c (die): If we're dying with a fatal error (not that a
2196 command has failed), write back any leftover tokens before we go.
2198 * job.c (set_child_handler_action_flags): If there are jobs
2199 waiting for the load to go down, set an alarm to go off in 1
2200 second. This allows us to wake up from a potentially long-lasting
2201 read() and start a new job if the load has gone down. Turn it off
2203 (job_noop): Dummy signal handler function.
2204 (new_job): Invoke it with the new semantics.
2206 * docs/make.texi: Document secondary expansion. Various cleanups
2209 2005-05-03 Paul D. Smith <psmith@gnu.org>
2211 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2212 the targets which are to ultimately be made are called "goals";
2213 see the GNU make manual. Also, MAKECMDGOALS, etc.
2215 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2216 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2217 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2219 2005-05-02 Paul D. Smith <psmith@gnu.org>
2221 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2222 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2223 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2224 functions to vmsjobs.c. #include it into jobs.c.
2226 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2227 jobserver tokens. I found that this happens when an exported
2228 recursive variable contains a $(shell ...) function reference: in
2229 this situation we could "forget" to write back a token.
2231 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2232 we have. It's not reliable to depend on the number of children in
2233 our linked list so keep a separate count.
2234 (new_job): Check jobserver_tokens rather than children &&
2235 waiting_jobs. Increment jobserver_tokens when we get one.
2236 (free_child): If jobserver_tokens is 0, internal error. If it's
2237 >1, write a token back to the jobserver pipe (we don't write a
2238 token for the "free" job). Decrement jobserver_tokens.
2240 * main.c: Add variable master_job_slots.
2241 (main): Set it to hold the number of jobs requested if we're the
2242 master process, when using the jobserver.
2243 (die): Sanity checks: first test jobserver_tokens to make sure
2244 this process isn't holding any tokens we didn't write back.
2245 Second, if master_job_slots is set count the tokens left in the
2246 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2248 2005-04-24 Paul D. Smith <psmith@gnu.org>
2250 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2251 with -l# can lose jobserver tokens, because waiting jobs are not
2252 consulted properly when checking for the "free" token.
2254 * job.c (free_child): Count waiting_jobs as having tokens.
2255 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2256 handle jobs waiting for the load to drop.
2258 2005-04-23 Paul D. Smith <psmith@gnu.org>
2260 * main.c (main): Be careful to not core if a variable setting in
2261 the environment doesn't contain an '='. This is illegal but can
2262 happen in broken setups.
2263 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2265 2005-04-12 Paul D. Smith <psmith@gnu.org>
2267 The second expansion feature causes significant slowdown. Timing
2268 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2269 read the makefile before the feature, to 11+s to do the same
2270 operations after the feature. Additionally, memory usage
2271 increased drastically. To fix this I added some intelligence that
2272 avoids the overhead of the second expansion unless it's required.
2274 * dep.h: Add a new boolean field, need_2nd_expansion.
2276 * read.c (eval): When creating the struct dep for the target,
2277 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2278 (record_files): If there's a "%" in a static pattern rule, it gets
2279 converted to "$*" so set need_2nd_expansion to 1.
2281 * file.c (expand_deps): Rework to be more efficient. Only perform
2282 initialize_file_variables(), set_file_variables(), and
2283 variable_expand_for_file() if the need_2nd_expansion is set.
2285 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2286 (pattern_search): Ditto.
2287 * main.c (handle_non_switch_argument): Ditto.
2289 * read.c (read_all_makefiles): Ditto.
2290 (eval_makefile): Ditto.
2292 2005-04-07 Paul D. Smith <psmith@gnu.org>
2294 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2295 * variable.c (sync_Path_environment): Ditto.
2296 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2298 * main.c (main): Define the .FEATURES variable.
2299 * NEWS: Announce .FEATURES.
2300 * doc/make.texi (Special Variables): Document .FEATURES.
2302 * remake.c (check_dep): If a file is .PHONY, update it even if
2303 it's marked intermediate. Fixes Savannah bug #12331.
2305 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2307 * file.c (expand_deps): Factor out the second expansion and
2308 prerequisite line parsing logic from snap_deps().
2310 * file.c (snap_deps): Use expand_deps(). Expand and parse
2311 prerequisites of the .SUFFIXES special target first. Fixes
2312 Savannah bug #12320.
2314 2005-03-13 Paul D. Smith <psmith@gnu.org>
2316 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2319 2005-03-11 Paul D. Smith <psmith@gnu.org>
2321 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2322 available, not undefined (from Earnie Boyd).
2324 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2326 * implicit.c (pattern_search): Mark an intermediate target as
2327 precious if it happened to be a prerequisite of some (other)
2328 target. Fixes Savannah bug #12267.
2330 2005-03-09 Paul D. Smith <psmith@gnu.org>
2332 * read.c (eval_makefile): Add alloca(0).
2333 (eval_buffer): Ditto.
2335 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2337 * main.c (main): Use o_file instead of o_default when defining
2338 the .DEFAULT_TARGET special variable.
2339 * read.c (eval): Use define_variable_global() instead of
2340 define_variable() when setting new value for the .DEFAULT_TARGET
2341 special variable. Fixes Savannah bug #12266.
2343 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2345 * imlicit.c (pattern_search): Mark files for which an implicit
2346 rule has been found as targets. Fixes Savannah bug #12202.
2348 2005-03-04 Paul D. Smith <psmith@gnu.org>
2351 * doc/make.texi (Automatic Variables): Document $|.
2353 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2355 * read.c (record_files): Instead of substituting % with
2356 actual stem value in dependency list replace it with $*.
2357 This fixes stem triple expansion bug.
2359 * implicit.c (pattern_search): Copy stem to a separate
2360 buffer and make it a properly terminated string. Assign
2361 this buffer instead of STEM (which is not terminated) to
2362 f->stem. Instead of substituting % with actual stem value
2363 in dependency list replace it with $*. This fixes stem
2364 triple expansion bug.
2366 2005-03-01 Paul D. Smith <psmith@gnu.org>
2368 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2369 on Windows, as it takes a handle not a pid. Just exit.
2370 Fix from patch #3679, provided by Alessandro Vesely.
2372 * configure.in: Update check for sys_siglist[] from autoconf manual.
2373 * signame.c (strsignal): Update to use the new autoconf macro.
2375 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2377 * read.c (record_files): Add a check for the list of prerequisites
2378 of a static pattern rule being empty. Fixes Savannah bug #12180.
2380 2005-02-28 Paul D. Smith <psmith@gnu.org>
2382 * doc/make.texi (Text Functions): Update docs to allow the end
2383 ordinal for $(wordlist ...) to be 0.
2384 * function.c (func_wordlist): Fail if the start ordinal for
2385 $(wordlist ...) is <1. Matches documentation.
2386 Resolves Savannah support request #103195.
2388 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2389 previously we were stopping when !-q, exactly the opposite. This
2390 has been wrong since version 1.34, in 1994!
2391 (update_file): If we got an error don't break out to run more
2392 double-colon rules: just return immediately.
2393 Fixes Savannah bug #7144.
2395 2005-02-27 Paul D. Smith <psmith@gnu.org>
2397 * misc.c (end_of_token): Make argument const.
2398 * make.h: Update prototype.
2400 * function.c (abspath, func_realpath, func_abspath): Use
2401 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2402 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2403 * read.c (record_files): Ditto.
2404 * variable.c (do_variable_definition): Ditto.
2406 * function.c (func_error): Create a new function $(info ...) that
2407 simply prints the message to stdout with no extras.
2408 (function_table_init): Add new function to the table.
2409 * NEWS: Add $(info ...) reference.
2410 * doc/make.texi (Make Control Functions): Document it.
2412 New feature: if the system supports symbolic links, and the user
2413 provides the -L/--check-symlink-time flag, then use the latest
2414 mtime between the symlink(s) and the target file.
2416 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2417 readlink(). If both are available, define MAKE_SYMLINKS.
2418 * main.c: New variable: check_symlink_flag.
2419 (usage): Add a line for -L/--check-symlink-times to the help string.
2420 (switches): Add -L/--check-symlink-times command line argument.
2421 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2422 print a warning and disable it again.
2423 * make.h: Declare check_symlink_flag.
2424 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2425 if the file is a symlink then check each link in the chain and
2426 choose the NEWEST mtime we find as the mtime for the file. The
2427 newest mtime might be the file itself!
2428 * NEWS: Add information about this new feature.
2429 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2431 Avoid core dumps described in Savannah bug # 12124:
2433 * file.c: New variable snapped_deps remember whether we've run
2435 (snap_deps): Set it.
2436 * filedef.h: Extern it.
2437 * read.c (record_files): Check snapped_deps; if it's set then
2438 we're trying to eval a new target/prerequisite relationship from
2439 within a command script, which we don't support. Fatal.
2441 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2443 Implementation of the .DEFAULT_TARGET special variable.
2445 * read.c (eval): If necessary, update default_target_name when
2447 * read.c (record_files): Update default_target_file if
2448 default_target_name has changed.
2449 * main.c (default_target_name): Define.
2450 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2451 default_target_name is set use default_target_file as a root
2453 * filedef.h (default_target_name): Declare.
2454 * dep.h (free_dep_chain):
2455 * misc.c (free_dep_chain): Change to operate on struct nameseq
2456 and change name to free_ns_chain.
2457 * file.c (snap_deps): Update to use free_ns_chain.
2459 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2461 Implementation of the second expansion in explicit rules,
2462 static pattern rules and implicit rules.
2464 * read.c (eval): Refrain from chopping up rule's dependencies.
2465 Store them in a struct dep as a single dependency line. Remove
2466 the code that implements SySV-style automatic variables.
2468 * read.c (record_files): Adjust the code that handles static
2469 pattern rules to expand all percents instead of only the first
2470 one. Reverse the order in which dependencies are stored so that
2471 when the second expansion reverses them again they appear in
2472 the makefile order (with some exceptions, see comments in
2473 the code). Remove the code that implements SySV-style automatic
2476 * file.c (snap_deps): Implement the second expansion and chopping
2477 of dependency lines for explicit rules.
2479 * implicit.c (struct idep): Define an auxiliary data type to hold
2480 implicit rule's dependencies after stem substitution and
2483 * implicit.c (free_idep_chain): Implement.
2485 * implicit.c (get_next_word): Implement helper function for
2486 parsing implicit rule's dependency lines into words taking
2487 into account variable expansion requests. Used in the stem
2490 * implicit.c (pattern_search): Implement the second expansion
2491 for implicit rules. Also fixes bug #12091.
2493 * commands.h (set_file_variables): Declare.
2494 * commands.c (set_file_variables): Remove static specifier.
2496 * dep.h (free_dep_chain): Declare.
2497 * misc.c (free_dep_chain): Implement.
2499 * variable.h (variable_expand_for_file): Declare.
2500 * expand.c (variable_expand_for_file): Remove static specifier.
2502 * make.h (strip_whitespace): Declare.
2503 * function.c (strip_whitespace): Remove static specifier.
2505 2005-02-26 Paul D. Smith <psmith@gnu.org>
2507 * main.c (main): Check for ferror() when reading makefiles from stdin.
2508 Apparently some shells in Windows don't close pipes properly and
2511 2005-02-24 Jonathan Grant <jg@jguk.org>
2513 * configure.in: Add MinGW configuration options, and extra w32 code
2515 * Makefile.am: Add MinGW configuration options, and extra w32 code
2517 * main.c: Determine correct program string (after last \ without .exe).
2518 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2520 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2521 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2522 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2523 environment support.
2525 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2527 * function.c (func_shell): When initializing error_prefix, check
2528 that reading file name is not null. This fixes long-standing
2529 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2531 2005-02-09 Paul D. Smith <psmith@gnu.org>
2533 * maintMakefile: Update the CVS download URL to simplify them.
2534 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2535 downloading the .texi files from Savannah now.
2537 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2539 * main.c (handle_non_switch_argument): Only add variables to
2540 command_variables if they're not already there: duplicate settings
2541 waste space and can be confusing to read.
2543 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2544 this header is never included by non-WINDOWS32 code, and it
2545 requires <config.h> to define which isn't always included first.
2547 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2548 testing MINGW32 versions.
2550 * main.c (log_working_directory): flush stdout to be sure the WD
2551 change is printed before any stderr messages show up.
2553 2005-02-01 Paul D. Smith <psmith@gnu.org>
2555 * maintMakefile (po_repo): Update the GNU translation site URL.
2557 2004-12-01 Paul D. Smith <psmith@gnu.org>
2559 * main.c (main): Change char* env_shell to struct variable shell_var.
2560 * variable.c (target_environment): Use new shell_var.
2562 2004-11-30 Paul D. Smith <psmith@gnu.org>
2564 * configure.in: The old way we avoided creating build.sh from
2565 build.sh.in before build.sh.in exists doesn't work anymore; we
2566 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2567 the help!). This also keeps automake from complaining.
2568 * Makefile.am (README): Add a dummy target so automake won't
2569 complain that this file doesn't exist when we checkout from CVS.
2570 * maintMakefile (.dep_segment): Rewrite this rule since newer
2571 versions of automake don't provide DEP_FILES.
2573 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2575 Implementation of `realpath' and `abspath' built-in functions.
2577 * configure.in: Check for realpath.
2578 * function.c (abspath): Return an absolute file name that does
2579 not contain any `.' or `..' components, nor repeated `/'.
2580 * function.c (func_abspath): For each name call abspath.
2581 * function.c (func_realpath): For each name call realpath
2582 from libc or delegate to abspath if realpath is not available.
2583 * doc/make.texi (Functions for File Names): Document new functions.
2584 * doc/make.texi (Quick Reference): Ditto.
2586 2004-11-28 Paul D. Smith <psmith@gnu.org>
2588 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2589 arguments. Fixes bug #10252.
2591 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2593 * main.c (main): Set SHELL to v_noexport by default. Remember the
2594 original environment setting of SHELL in the env_shell variable.
2595 * main.h: Export new env_shell variable.
2596 * variable.c (target_environment): If we find a v_noexport
2597 variable for SHELL, add a SHELL variable with the env_shell value.
2598 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2599 * doc/make.texi (Variables/Recursion): Ditto.
2601 2004-11-28 Paul D. Smith <psmith@gnu.org>
2603 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2604 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2605 Patch by Alessandro Vesely.

2609 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2610 the command line if it's inside a string.
2611 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2613 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2615 * function.c (func_lastword): New function: return last word
2616 from the list of words.
2617 * doc/make.texi: Document $(lastword ). Fix broken links in
2618 Quick Reference section.
2620 2004-10-06 Paul D. Smith <psmith@gnu.org>
2622 Apply patch from Alessandro Vesely, provided with bug # 9748.
2623 Fix use of tmpnam() to work with Borland C.
2625 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2626 construction of a temporary filename, and call new function
2627 create_batch_filename().
2628 (create_batch_filename) [WINDOWS32]: New function to create a
2631 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2633 * read.c (record_target_var): Expand simple pattern-specific
2635 * variable.c (initialize_file_variables): Do not expand simple
2636 pattern-specific variable.
2638 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2640 * remake.c (update_file_1): When rebuilding makefiles inherit
2641 dontcare flag from a target that triggered update.
2643 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2645 * variable.c (initialize_file_variables): Mark pattern-specific
2646 variable as a per-target and copy export status.
2648 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2650 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2652 * implicit.c (pattern_search): When considering an implicit rule's
2653 prerequisite check that it is actually a target rather then
2654 just an entry in the file hashtable.
2656 2004-09-21 Paul D. Smith <psmith@gnu.org>
2658 * read.c (readstring): Fix some logic errors in backslash handling.
2659 (eval): Remove some unnecessary processing in buffer handling.
2660 (record_target_var): Assert that parse_variable_definition() succeeded.
2661 Reported by: Markus Mauhart <qwe123@chello.at>.
2663 * misc.c: Removed the sindex() function. All instances of this
2664 function were trivially replaceable by the standard strstr()
2665 function, and that function will always have better (or certainly
2666 no worse) performance than the very simple-minded algorithm
2667 sindex() used. This can matter with complex makefiles.
2668 * make.h: Remove the prototype for sindex().
2669 * function.c (subst_expand): Convert sindex() call to strstr().
2670 This means we no longer need to track the TLEN value so remove that.
2671 (func_findstring): Convert sindex() to strstr().
2672 * commands.c (chop_commands): Convert sindex() calls to strstr().
2673 Suggested by: Markus Mauhart <qwe123@chello.at>.
2675 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2676 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2677 If SHELL is set to CMD.EXE then assume it's batch-mode and
2678 non-unixy. I wrote the code differently from the patch, though,
2679 to make it safer. This also resolves bug #9174.
2681 2004-09-20 Paul D. Smith <psmith@gnu.org>
2683 * expand.c (variable_expand_string): Modify to invoke
2684 patsubst_expand() instead of subst_expand(); the latter didn't
2685 handle suffix patterns correctly.
2686 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2687 was used only from variable_expand_string() and is no longer used
2689 (func_subst): Ditto, on call to subst_expand().
2690 (patsubst_expand): Require the percent pointers to point to the
2691 character after the %, not to the % itself.
2692 * read.c (record_files): New call criteria for patsubst_expand().
2693 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2694 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2696 2004-09-19 Paul D. Smith <psmith@gnu.org>
2698 * function.c (subst_expand): Fix a check in by_word: look for a
2699 previous blank if we're beyond the beginning of the string, not
2700 the beginning of the word.
2701 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2703 2004-05-16 Paul D. Smith <psmith@gnu.org>
2705 * remake.c (update_goal_chain): Change the argument specifying
2706 whether we're rebuilding makefiles to be a global variable,
2707 REBUILDING_MAKEFILES.
2708 (complain): Extract the code that complains about no rules to make
2709 a target into a separate function.
2710 (update_file_1): If we tried to rebuild a file during the makefile
2711 rebuild phase and it was dontcare, then no message was printed.
2712 If we then try to build the same file during the normal build,
2713 print a message this time.
2714 (remake_file): Don't complain about un-remake-able files when
2715 we're rebuilding makefiles.
2717 2004-05-11 Paul D. Smith <psmith@gnu.org>
2719 * job.c (construct_command_argv_internal): OS/2 patches from
2720 Andreas Buening <andreas.buening@nexgo.de>.
2722 2004-05-10 Paul D. Smith <psmith@gnu.org>
2724 * remake.c (update_file): Don't walk the double-colon chain unless
2725 this is a double-colon rule. Fix suggested by Boris Kolpackov
2726 <boris@kolpackov.net>.
2728 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2729 * readme.vms: New section describing OpenVMS support and issues.
2730 * default.c (default_variables): Add support for IA64.
2731 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2732 without some privilege aborts make with the error
2733 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2734 pressing Ctrl+Y and the input device is no terminal. The change
2735 catches this error and just continues.
2737 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2739 2004-04-25 Paul D. Smith <psmith@gnu.org>
2741 * commands.c (set_file_variables): Set $< properly in the face of
2742 order-only prerequisites.
2743 Patch from Boris Kolpackov <boris@kolpackov.net>
2745 2004-04-21 Bob Byrnes <byrnes@curl.com>
2747 * main.c (main): Notice failures to remake makefiles.
2749 2004-03-28 Paul D. Smith <psmith@gnu.org>
2751 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2753 * job.c: No default shell for RISC OS.
2754 (load_too_high): Hard-code the return to 1.
2755 (construct_command_argv_internal): No sh_chars or sh_cmds.
2756 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2758 2004-03-20 Paul D. Smith <psmith@gnu.org>
2760 * variable.c (do_variable_definition): Don't append from the
2761 global set if a previous non-appending target-specific variable
2762 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2765 * expand.c (reference_variable): Don't give up on variables with
2766 no value that have the target-specific append flag set: they might
2767 have a value after all. Reported by Oliver Schmidt
2768 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2769 <nikulin@dx1cmd.inp.nsk.su>.
2771 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2772 refer to absolute pathnames in directories that don't exist: some
2773 portion of the makefile could create those directories before we
2774 match the pattern. Fixes bugs #775 and #108.
2776 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2778 * main.c (main): Free makefile_mtimes if we have any.
2779 * README.W32.template: Update documentation for the current status
2780 of the MS-Windows port.
2781 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2782 environment variable is sometimes already defined which causes the
2784 * main.c (debug_signal_handler): Only define this function if
2785 SIGUSR1 is available.
2787 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2789 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2790 * README.OS2.template: Documentation updates.
2791 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2792 link line for safety.
2793 * maintMakefile (build.sh.in): Remove an extraneous ")".
2794 * job.c (child_execute_job): Close saved FDs.
2795 * job.c (exec_command) [OS/2]: exec_command(): If the command
2796 can't be exec'ed and if the shell is not Unix-sh, then try again
2797 with argv = { "cmd", "/c", ... }. Normally, this code is never
2798 reached for the cmd shell unless the command really doesn't exist.
2799 (construct_command_argv_internal) [OS/2]: The code for cmd
2800 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2801 The CMD builtin commands are case insensitive so use strcasecmp().
2803 2004-03-19 Paul D. Smith <psmith@gnu.org>
2805 * read.c (do_define): Re-order line counter increment so the count
2806 is accurate (we were losing one line per define). Reported by
2807 Dave Yost <Dave@Yost.com>.
2809 2004-03-06 Paul D. Smith <psmith@gnu.org>
2811 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2813 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2814 * misc.c (message,error,fatal): Ditto.
2815 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2816 * config.h.W32.template: Ditto.
2817 * config.h-vms.template: Ditto.
2818 * config.ami.template: Ditto.
2820 2004-03-04 Paul D. Smith <psmith@gnu.org>
2822 * README.template: Add a note about broken /bin/sh on SunOS
2823 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2825 * misc.c (message, error, fatal): Don't use "..." if we're using
2826 varargs. ansi2knr should handle this but it doesn't work: it
2827 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2828 done. On many systems (SunOS for example) va_dcl is a #define.
2829 So, force the use of the non-"..." version on pre-ANSI compilers.
2831 * maintMakefile (sign-dist): Create some rules to help automate
2832 the new GNU ftp upload method.
2834 2004-02-24 Paul D. Smith <psmith@gnu.org>
2836 * config.h.W32.template: Add HAVE_STDARG_H
2837 * config.h-vms.template: Ditto.
2838 * config.ami.template: Ditto.
2840 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2842 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2843 * build_w32.bat: Remove extra "+".
2845 2004-02-23 Paul D. Smith <psmith@gnu.org>
2847 * make.h: Create an UNUSED macro to mark unused parameters.
2848 * (many): Clean up warnings by applying UNUSED, fixing
2849 signed/unsigned incompatibilities, etc.
2851 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2853 * filedef.h: Name the command_state enumeration.
2854 * file.c (set_command_state): Use the enumeration in the function
2857 * configure.in: Explicitly set SET_MAKE to empty, to disable
2858 MAKE=make even when no make already exists. Fix bug #3823.
2860 2004-02-22 Paul D. Smith <psmith@gnu.org>
2862 * maintMakefile: Perl script to clean up all non-CVS files. Use
2863 it on all the subdirectories for the cvs-clean target.
2865 * main.c (decode_switches): Require non-empty strings for all our
2866 string command-line options. Fixes Debian bug # 164165.
2868 * configure.in: Check for stdarg.h and varargs.h.
2869 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2870 for printing messages.
2871 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2876 A number of patches for OS/2 support from Andreas Buening
2877 <andreas.buening@nexgo.de>:
2879 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2880 disable the SIGCHLD handler.
2881 (reap_children) [OS/2]: Remove special handling of job_rfd.
2882 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2883 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2884 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2885 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2886 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2889 2004-02-21 Paul D. Smith <psmith@gnu.org>
2891 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2892 <mail@kristov.de> reports that if process_begin() fails we don't
2893 handle the error condition correctly in all cases.
2894 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2895 to have a newline on the message.
2897 * job.c (construct_command_argv_internal): Add "test" to UNIX
2898 sh_cmds[]. Fixes Savannah bug # 7606.
2900 2004-02-04 Paul D. Smith <psmith@gnu.org>
2902 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2903 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2904 Hartmut Becker <Hartmut.Becker@hp.com>.
2906 2004-01-21 Paul D. Smith <psmith@gnu.org>
2908 * job.c (load_too_high): Implement an algorithm to control the
2909 "thundering herd" problem when using -l to control job creation
2910 via the load average. The system only recomputes the load once a
2911 second but we can start many jobs in a second. To solve this we
2912 keep track of the number of jobs started in the last second and
2913 apply a weight to try to guess what a correct load would be.
2914 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2915 Also fixes bug #4693.
2916 (reap_children): Decrease the job count for this second.
2917 (start_job_command): Increase the job count for this second.
2919 * read.c (conditional_line): Expand the text after ifn?def before
2920 checking to see if it's a single word. Fixes bug #7257.
2922 2004-01-09 Paul D. Smith <psmith@gnu.org>
2924 * file.c (print_file): Recurse to print all targets in
2925 double-colon rules. Fixes bug #4518, reported (with patch) by
2926 Andrew Chatham <chatham@google.com>.
2928 2004-01-07 Paul D. Smith <psmith@gnu.org>
2930 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2931 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2932 AC_FUNC_SETVBUF_REVERSED.
2934 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2935 (MAKE Variable): Fix Savannah bug #4898.
2937 * job.c (construct_command_argv_internal): Add "!" to the list of
2938 shell escape chars. POSIX sh allows it to appear before a
2939 command, to negate the exit code. Fixes bug #6404.
2941 * implicit.c (pattern_search): When matching an implicit rule,
2942 remember which dependencies have the ignore_mtime flag set.
2943 Original fix provided in Savannah patch #2349, by Benoit
2944 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2946 2003-11-22 Paul D. Smith <psmith@gnu.org>
2948 * README.W32.template (Outputs): Clarification on -j with
2949 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2952 2003-11-02 Paul D. Smith <psmith@gnu.org>
2954 * function.c (func_if): Strip all the trailing whitespace from the
2955 condition, then don't expand it. Fixed bug # 5798.
2957 * expand.c (recursively_expand_for_file): If we're expanding a
2958 variable with no file context, then use the variable's context.
2961 2003-10-21 Paul D. Smith <psmith@gnu.org>
2963 * main.c (log_working_directory): Add newlines to printf()s.
2965 * README.cvs: Add a note to ignore warnings during autoreconf.
2967 * maintMakefile (po_repo): Set a new URL for PO file updates.
2968 (get-config/config.guess get-config/config.sub): Get these files
2969 from the Savannah config project instead of ftp.gnu.org.
2971 2003-10-05 Paul Eggert <eggert@twinsun.com>
2973 * main.c (main): Avoid potential subscript error if environ has
2976 2003-08-22 Paul D. Smith <psmith@gnu.org>
2978 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
2979 systems which don't yet implement the C89 standard :-/.
2981 2003-07-18 Paul D. Smith <psmith@gnu.org>
2983 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
2984 [WINDOWS32]: Initialize hash.
2986 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
2988 * dir.c (read_dirstream): Provide a workaround for broken versions of
2989 the MinGW dirent structure.
2991 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2993 * w32/include/dirent.h: Add __MINGW32__ filter.
2995 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2997 * make.h: Add global declaration of *make_host.
2998 * main.c (print_usage): Remove local declaration of *make_host.
2999 (print_version): Display "This program built for ..." after Copyright
3002 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3004 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
3005 execution of "makeinfo --html make.texi".
3007 2003-04-30 Paul D. Smith <psmith@gnu.org>
3009 * build.template: Make some changes to maybe allow this script to
3010 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
3012 * README.OS2.template: New file for OS/2 support. Original
3013 contributed by Andreas Buening.
3014 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
3017 2003-04-19 Paul D. Smith <psmith@gnu.org>
3019 Fix bug #1405: allow a target to match multiple pattern-specific
3022 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3023 variable.c, where they've always belonged.
3024 * rule.h: Move the prototypes and struct pattern_var as well.
3025 * variable.c (initialize_file_variables): Invoke
3026 lookup_pattern_var() in a loop, until no more matches are found.
3027 If a match is found, create a new variable set for the target's
3028 pattern variables. Then merge the contents of each matching
3029 pattern variable set into the target's pattern variable set.
3030 (lookup_pattern_var): Change this function to be usable
3031 in a loop. It takes a starting position: if NULL, start at the
3032 beginning; if non-NULL, start with the pattern variable after that
3033 position, and return the next matching pattern.
3034 (create_pattern_var): Create a unique instance of
3035 pattern-specific variables for every definition in the makefile.
3036 Don't combine the same pattern together. This allows us to
3037 process the variable handling properly even when the same pattern
3038 is used multiple times.
3039 (parse_variable_definition): New function: break out the parsing
3040 of a variable definition line from try_variable_definition.
3041 (try_variable_definition): Call parse_variable_definition to
3043 (print_variable_data_base): Print out pattern-specific variables.
3044 * variable.h (struct variable): Remember when a variable is
3045 conditional. Also remember its flavor.
3046 (struct pattern_var): Instead of keeping a variable set, we just
3047 keep a single variable for each pattern.
3048 * read.c (record_target_var): Each pattern variable contains only a
3049 single variable, not a set, so create it properly.
3050 * doc/make.texi (Pattern-specific): Document the new behavior.
3052 2003-04-17 Paul D. Smith <psmith@gnu.org>
3054 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3055 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3056 file/directory naming rules for VMS so I can't tell whether this
3059 2003-04-09 Paul D. Smith <psmith@gnu.org>
3061 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3062 DOS-style pathnames: backslash separators and drive specifiers.
3064 2003-03-28 Paul D. Smith <psmith@gnu.org>
3066 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3067 the intermediate flag on all targets. Fixes bug #2515.
3069 2003-03-24 Paul D. Smith <psmith@gnu.org>
3071 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3072 Upgrade to autoconf 2.57 and automake 1.7.3.
3074 * job.c: More OS/2 changes from Andreas Buening.
3076 * file.c (print_file): Fix variable initialization.
3079 * remake.c (notice_finished_file):
3081 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3082 some calls (like readdir()) return NULL in valid situations
3083 without resetting errno. Fixes bug #2846.
3085 2003-02-25 Paul D. Smith <psmith@gnu.org>
3087 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3089 * job.c (_is_unixy_shell) [OS/2]: New function.
3090 Set default shell to /bin/sh.
3091 (reap_children): Close the job_rfd pipe here since we don't use a
3093 (set_child_handler_action_flags): define this to empty on OS/2.
3094 (start_job_command): Close the jobserver pipe and use
3095 child_execute_job() instead of fork/exec.
3096 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3097 rather than exec'ing, then reconfigure stdin/stdout.
3098 (exec_command): Rewrite to use spawn instead of exec. Return the
3101 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3102 in DOS. Handle the TEMP environment variable as in DOS. Don't
3103 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3104 use -j in DOS mode. Use child_execute_job() instead of
3107 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3110 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3111 prototypes that return values.
3113 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3115 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3116 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3118 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3121 2003-02-24 Paul D. Smith <psmith@gnu.org>
3123 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3124 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3125 (child_execute_job) [VMS]: Handle error status properly.
3126 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3128 * function.c (func_shell): Use EINTRLOOP() while reading from the
3129 subshell pipe (Fixes bug #2502).
3130 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3132 * main.c (main): Ditto.
3134 2003-01-30 Paul D. Smith <psmith@gnu.org>
3136 * read.c (eval): eval() was not fully reentrant, because the
3137 collapsed buffer was static. Change it to be an automatic
3138 variable so that eval() can be invoked recursively.
3140 (eval): Apply patch # 1022: fix memory reference error on long
3141 target-specific variable lines.
3142 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3144 * function.c (check_numeric): Combine the is_numeric() function
3145 into this function, since it's only called from one place.
3146 Constify this function. Have it print the incorrect string in the
3147 error message. Fixes bug #2407.
3148 (strip_whitespace): Constify.
3149 (func_if): Constify.
3150 * expand.c (expand_argument): Constify.
3152 2003-01-29 Paul D. Smith <psmith@gnu.org>
3154 Fix bug # 2169, also reported by other people on various systems.
3156 * make.h: Some systems, such as Solaris and PTX, do not fully
3157 implement POSIX-compliant SA_RESTART functionality; important
3158 system calls like stat() and readdir() can still fail with EINTR
3159 even if SA_RESTART has been set on the signal handler. So,
3160 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3161 EINTR for system calls which return -1 or 0 (NULL), respectively,
3163 Also, remove the old atomic_stat()/atomic_readdir() and
3164 HAVE_BROKEN_RESTART handling.
3166 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3168 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3169 * remake.c (touch_file): Ditto.
3171 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3172 * read.c (construct_include_path): Ditto.
3173 * remake.c (name_mtime): Ditto.
3174 * vpath.c (selective_vpath_search): Ditto.
3175 * dir.c (find_directory): Ditto.
3176 (local_stat): Ditto.
3177 (find_directory): Use ENULLLOOP() to wrap opendir().
3178 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3180 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3181 atomic_readdir() handling.
3183 2003-01-22 Paul D. Smith <psmith@gnu.org>
3185 * function.c (func_call): Fix Bug #1744. If we're inside a
3186 recursive invocation of $(call ...), mask any of the outer
3187 invocation's arguments that aren't used by this one, so that this
3188 invocation doesn't "inherit" them accidentally.
3190 2002-12-05 Paul D. Smith <psmith@gnu.org>
3192 * function.c (subst_expand): Valery Khamenia reported a
3193 pathological performance hit when doing substitutions on very
3194 large values with lots of words: turns out we were invoking
3195 strlen() a ridiculous number of times. Instead of having each
3196 call to sindex() call strlen() again, keep track of how much of
3197 the text we've seen and pass the length to sindex().
3199 2002-11-19 Paul D. Smith <psmith@gnu.org>
3201 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3204 2002-11-16 Paul D. Smith <psmith@gnu.org>
3206 * NMakefile.template (OBJS): Add hash.c object file.
3207 * SMakefile.template (srcs): Ditto.
3208 * Makefile.ami (objs): Ditto.
3209 * build_w32.bat: Ditto.
3211 * Makefile.DOS.template: Remove extra dependencies.
3213 2002-10-25 Paul D. Smith <psmith@gnu.org>
3215 * expand.c (install_variable_buffer): New function. Install a new
3216 variable_buffer context and return the previous one.
3217 (restore_variable_buffer): New function. Free the current
3218 variable_buffer context and put a previously saved one back.
3219 * variable.h: Prototypes for {install,restore}_variable_buffer.
3220 * function.c (func_eval): Push a new variable_buffer context
3221 before we eval, then restore the old one when we're done.
3224 * read.c (install_conditionals): New function. Install a new
3225 conditional context and return the previous one.
3226 (restore_conditionals): New function. Free the current
3227 conditional context and put a previously saved one back.
3228 (eval): Use the {install,restore}_conditionals for "include"
3230 (eval_buffer): Use {install,restore}_conditionals to preserve the
3231 present conditional state before we evaluate the buffer.
3234 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3236 (Recursion): Add a variable index entry for CURDIR.
3238 * README.cvs: Update to appropriate versions.
3239 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3240 don't need to copy loadavg.c: automake is smart enough to create
3241 it for me. Still have a bug in automake related to ansi2knr tho.
3243 2002-10-14 Paul D. Smith <psmith@gnu.org>
3245 * remake.c (notice_finished_file): Only touch targets if they have
3246 at least one command (as per POSIX). Resolve Bug #1418.
3248 * *.c: Convert to using ANSI C-style function definitions.
3249 * Makefile.am: Enable the ansi2knr feature of automake.
3250 * configure.in: ditto.
3252 2002-10-13 Paul D. Smith <psmith@gnu.org>
3254 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3255 for automatic variable values like $^, etc. In the case of very
3256 large lists of prerequisites this causes problems. Instead reuse
3257 a static buffer (resizeable) for each variable.
3259 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3260 target-specific variable definitions. Check for it and set an
3262 (record_target_var): Set the export field to v_export if the
3263 "exported" flag is set.
3264 * doc/make.texi (Target-specific): Document the ability to use
3267 * doc/make.texi: Change the name of the section on automatic
3268 variables from "Automatic" to "Automatic Variables". Added text
3269 clarifying the scope of automatic variables.
3271 2002-10-04 Paul D. Smith <psmith@gnu.org>
3273 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3275 (record_files): Ditto.
3277 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3278 the search for the '=' to only within the enclosing parens.
3280 2002-10-03 Paul D. Smith <psmith@gnu.org>
3282 Version 3.80 released.
3284 * dir.c: Change hash functions to use K&R function definition style.
3285 * function.c: Ditto.
3287 * variable.c: Ditto.
3289 Update to automake 1.7.
3291 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3292 (pdf): Remove this target as automake now provides one.
3294 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3296 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3298 * makefile.com: Updates for GNU make 3.80.
3299 * makefile.vms: Ditto.
3301 2002-09-23 Paul D. Smith <psmith@gnu.org>
3303 * read.c (enum make_word_type): Remove w_comment.
3304 (get_next_mword): Don't treat comment characters as special; where
3305 this function is used we will never see a comment (it's stripped
3306 before we get here) and treating comments specially means that
3307 targets like "foo\#bar" aren't handled properly.
3309 2002-09-18 Paul D. Smith <psmith@gnu.org>
3311 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3313 * read.c (eval): Expansion of arguments to export/unexport was
3314 ignoring all arguments after the first one. Change the algorithm
3315 to expand the whole line once, then parse the results.
3317 2002-09-17 Paul D. Smith <psmith@gnu.org>
3319 Fix Bug #940 (plus another bug I found while looking at this):
3321 * read.c (record_target_var): enter_file() will add a new entry if
3322 it's a double-colon target: we don't want to do that in this
3323 situation. Invoke lookup_file() and only enter_file() if it does
3324 not already exist. If the file we get back is a double-colon then
3325 add this variable to the "root" double-colon target.
3327 * variable.c (initialize_file_variables): If this file is a
3328 double-colon target but is not the "root" target, then initialize
3329 the root and make the root's variable list the parent of our
3332 2002-09-13 Paul D. Smith <psmith@gnu.org>
3334 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3336 * hash.c (round_up_2): Get rid of a warning.
3338 2002-09-12 Paul D. Smith <psmith@gnu.org>
3340 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3341 so it doesn't complain about getloadavg.c.
3343 * commands.c (set_file_variables): Make sure we always alloca() at
3344 least 1 character for the value of $? (for '\0').
3346 2002-09-11 Paul D. Smith <psmith@gnu.org>
3348 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3349 macro to use RESULT instead of the incorrect _RESULT_.
3351 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3352 and atomic_readdir(). We need to #include dirent.h to get this to
3354 * misc.c (atomic_readdir): Fix typos.
3356 2002-09-10 Paul D. Smith <psmith@gnu.org>
3358 * read.c (eval): Expand variable lists given to export and
3359 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3360 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3362 * doc/make.texi (Variables/Recursion): Document this.
3363 (Conditional Syntax): And here.
3365 2002-09-09 Paul D. Smith <psmith@gnu.org>
3367 * configure.in: Check for memmove().
3369 2002-09-07 Paul D. Smith <psmith@gnu.org>
3371 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3372 Michael Sterrett <msterret@coat.com> reports that while it has
3373 SA_RESTART, it does not work properly.
3375 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3376 that invokes stat() and loops to do it again if it returns EINTR.
3377 (atomic_readdir): Ditto, with readdir().
3379 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3380 and readdir() to atomic_stat() and atomic_readdir().
3382 2002-09-04 Paul D. Smith <psmith@gnu.org>
3384 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3385 reports that GNU make sometimes doesn't recognize that targets can
3386 be made, when directories can be created as prerequisites. He
3387 reports that changing the order of predicates in the DEP->changed
3388 flag test so that lookup_file() is always performed, solves this
3391 2002-08-08 Paul D. Smith <psmith@gnu.org>
3393 * configure.in: Require a newer version of gettext.
3395 * misc.c (perror_with_name): Translate the format string (for
3396 right-to-left language support).
3397 (pfatal_with_name): Ditto.
3399 * main.c: Create a static array of strings to store the usage
3400 text. This is done to facilitate translations.
3401 (struct command_switch): Remove argdesc and description fields.
3402 (switches): Remove values for obsolete fields.
3403 (print_usage): Print each element of the usage array.
3405 * hash.c: Change function definitions to be K&R style.
3407 2002-08-02 Paul D. Smith <psmith@gnu.org>
3409 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3410 this one because it's too hard to get right. We'll look at it for
3412 * main.c (main): Don't create the .TARGETS variable.
3413 * variable.c (handle_special_var): Don't handle .TARGETS.
3415 2002-08-01 Paul D. Smith <psmith@gnu.org>
3417 * main.c (switches): Add a new option, -B (--always-make). If
3418 specified, make will rebuild all targets that it encounters even
3419 if they don't appear to be out of date.
3420 (always_make_flag): New flag.
3421 * make.h: Extern always_make_flag.
3422 * remake.c (update_file_1): Check always_make_flag; if it's set we
3423 will always rebuild any target we can, even if none of its
3424 prerequisites are newer.
3427 * doc/make.texi (Shell Function): Make it clear that make
3428 variables marked as "export" are not passed to instances of the
3431 Add new introspection variable .VARIABLES and .TARGETS.
3433 * variable.c (handle_special_var): New function. If the variable
3434 reference passed in is "special" (.VARIABLES or .TARGETS),
3435 calculate the new value if necessary. .VARIABLES is handled here:
3436 walk through the hash of defined variables and construct a value
3437 which is a list of the names. .TARGETS is handled by
3438 build_target_list().
3439 (lookup_variable): Invoke handle_special_var().
3440 * file.c (build_target_list): Walk through the hask of known files
3441 and construct a list of the names of all the ones marked as
3443 * main.c (main): Initialize them to empty (and as simple variables).
3444 * doc/make.texi (Special Variables): Document them.
3445 * NEWS: Mention them.
3447 * variable.h (struct variable): Add a new flag "exportable" which
3448 is true if the variable name is valid for export.
3449 * variable.c (define_variable_in_set): Set "exportable" when a new
3450 variable is defined.
3451 (target_environment): Use the "exportable" flag instead of
3452 re-checking the name here... an efficiency improvement.
3454 2002-07-31 Paul D. Smith <psmith@gnu.org>
3456 * config.h-vms.template: Updates to build on VMS. Thanks to
3457 Brian_Benning@aksteel.com for helping verify the build.
3458 * makefile.com: Build the new hash.c file.
3459 * hash.h: Use strcpmi(), not stricmp(), in the
3460 HAVE_CASE_INSENSITIVE_FS case.
3462 2002-07-30 Paul D. Smith <psmith@gnu.org>
3464 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3465 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3466 Reported by <Brian_Benning@aksteel.com>.
3468 2002-07-10 Paul D. Smith <psmith@gnu.org>
3470 * variable.c (pop_variable_scope): Remove variable made unused by
3471 new hash infrastructure.
3472 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3473 comparisons as well as name comparisons.
3474 * variable.h: Add a prototype for new hash_init_function_table().
3475 * file.c (lookup_file): Remove variables made unused by new hash
3477 * dir.c (directory_contents_hash_2): Missing return of hash value.
3478 (dir_contents_file_exists_p): Remove variables made unused by new
3479 hash infrastructure.
3482 Installed Greg McGary's integration of the hash functions from the
3483 GNU id-utils package:
3485 2002-07-10 Greg McGary <greg@mcgary.org>
3487 * scripts/functions/filter-out: Add literals to to the
3488 pattern space in order to add complexity, and trigger
3489 use of an internal hash table. Fix documentation strings.
3490 * scripts/targets/INTERMEDIATE: Reverse order of files
3491 passed to expected `rm' command.
3493 2002-07-10 Greg McGary <greg@mcgary.org>

3585 2002-07-10 Paul D. Smith <psmith@gnu.org>
3587 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3588 prerequisite list. A real SysV make will expand the entire
3589 prerequisites list _twice_: we don't do that as it's a big
3590 backward-compatibility problem. We only replace those specific
3593 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3594 references left in the list of prerequisites. Check for .POSIX as
3595 we record targets, so we can disable non-POSIX behavior while
3596 reading makefiles as well as running them.
3597 (eval): Check the prerequisite list to see if we have anything
3598 that looks like a SysV prerequisite variable reference.
3600 2002-07-09 Paul D. Smith <psmith@gnu.org>
3602 * doc/make.texi (Prerequisite Types): Add a new section describing
3603 order-only prerequisites.
3605 * read.c (uniquize_deps): If we have the same file as both a
3606 normal and order-only prereq, get rid of the order-only prereq,
3607 since the normal one supersedes it.
3609 2002-07-08 Paul D. Smith <psmith@gnu.org>
3611 * AUTHORS: Added Greg McGary to the AUTHORS file.
3612 * NEWS: Blurbed order-only prerequisites.
3613 * file.c (print_file): Show order-only deps properly when printing
3616 * maintMakefile: Add "update" targets for wget'ing the latest
3617 versions of various external files. Taken from Makefile.maint in
3620 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3621 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3623 2002-07-07 Paul D. Smith <psmith@gnu.org>
3625 * po/*.po: Remove. We'll use wget to retrieve them at release
3628 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3629 rather than a shell you get an exception. Make sure we look up
3630 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3632 * remake.c (notice_finished_file): Fix handling of -t flag.
3633 Patch provided by Henning Makholm <henning@makholm.net>.
3635 * implicit.c (pattern_search): Some systems apparently run short
3636 of stack space, and using alloca() in this function caused an
3637 overrun. I modified it to use xmalloc() on the two variables
3638 which seemed like they might get large. Fixes Bug #476.
3640 * main.c (print_version): Update copyright notice to conform with
3642 (print_usage): Update help output.
3644 * function.c (func_eval): Create a new make function, $(eval
3645 ...). Expand the arguments, put them into a buffer, then invoke
3646 eval_buffer() on the resulting string.
3647 (func_quote): Create a new function, $(quote VARNAME). Inserts
3648 the value of the variable VARNAME without expanding it any
3651 * read.c (struct ebuffer): Change the linebuffer structure to an
3652 "eval buffer", which can be either a file or a buffer.
3653 (eval_makefile): Move the code in the old read_makefile() which
3654 located a makefile into here: create a struct ebuffer with that
3655 information. Have it invoke the new function eval() with that
3657 (eval_buffer): Create a new function that creates a struct ebuffer
3658 that holds a string buffer instead of a file. Have it invoke
3659 eval() with that ebuffer.
3660 (eval): New function that contains the guts of the old
3661 read_makefile() function: this function parses makefiles. Obtains
3662 data to parse from the provided ebuffer. Some modifications to
3663 make the flow of the function cleaner and clearer. Still could
3664 use some work here...
3665 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3666 contents of the define/endef variable from the ebuffer.
3667 (readstring): Read the next line from a string-style ebuffer.
3668 (readline): Read the next line from an ebuffer. If it's a string
3669 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3672 * dep.h (eval_buffer): Prototype eval_buffer();
3674 * variable.c (do_variable_definition): Make sure that all
3675 non-target-specific variables are registered in the global set.
3676 If we're invoked from an $(eval ...) we might be inside a $(call
3677 ...) or other function which has pushed a variable scope; we still
3678 want to define our variables from evaluated makefile code in the
3681 2002-07-03 Greg McGary <greg@mcgary.org>
3683 * dep.h (struct dep) [ignore_mtime]: New member.
3684 [changed]: convert to a bitfield.
3685 * implicit.c (pattern_search): Zero ignore_mtime.
3686 * main.c (main, handle_non_switch_argument): Likewise.
3687 * rule.c (convert_suffix_rule): Likewise.
3688 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3689 (read_makefile): Parse '|' in prerequisite list.
3690 (uniquize_deps): Consider ignore_mtime when comparing deps.
3691 * remake.c (update_file_1, check_dep): Don't force remake for
3692 dependencies that have d->ignore_mtime.
3693 * commands.c (FILE_LIST_SEPARATOR): New constant.
3694 (set_file_variables): Don't include a
3695 prerequisite in $+, $^ or $? if d->ignore_mtime.
3698 2002-06-18 Paul D. Smith <psmith@gnu.org>
3700 * make.texinfo: Updates for next revision. New date/rev/etc.
3701 Recreate all Info menus. Change license on the manual to the GNU
3702 Free Documentation License. A number of typos.
3703 (Variables Simplify): Don't use "-" before it's defined.
3704 (Automatic Prerequisites): Rewrite the target example to work
3705 properly if the compile fails. Remove incorrect comments about
3706 how "set -e" behaves.
3707 (Text Functions): Move the "word", "wordlist", "words", and
3708 "firstword" functions here, from "File Name Functions".
3709 * make-stds.texi: Update from latest GNU version.
3710 * fdl.texi: (created) Import the latest GNU version.
3712 2002-06-06 Paul D. Smith <psmith@gnu.org>
3714 * variable.c (do_variable_definition): New function: extract the
3715 part of try_variable_definition() that actually sets the value
3716 into a separate function.
3717 (try_variable_definition): Call do_variable_definition() after
3718 parsing the variable definition string.
3719 (define_variable_in_set): Make the name argument const.
3721 * variable.h (enum variable_flavor): Make public.
3722 (do_variable_definition): Create prototype.
3724 * read.c (read_all_makefiles): Create a new built-in variable,
3726 (read_makefile): Add each makefile read in to this variable value.
3728 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3730 * Makefile.DOS.template: Tweak according to changes in the
3731 distribution. Add back the dependencies of *.o files.
3733 * configh.dos.template: Synchronize with config.h.in.
3735 2002-05-09 Paul D. Smith <psmith@gnu.org>
3737 * file.c (file_timestamp_now): Use K&R function declaration.
3739 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3740 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3741 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3742 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3743 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3744 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3745 nlist.n_name is a pointer rather than an array.
3747 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3748 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3749 * configure.in: Use it instead of the old version.
3751 * main.c (main): Prefer setvbuf() to setlinebuf().
3753 2002-05-08 Paul D. Smith <psmith@gnu.org>
3755 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3756 (loadavg_LDADD): Ditto.
3758 2002-04-29 Paul D. Smith <psmith@gnu.org>
3760 * expand.c (recursively_expand_for_file): Rename
3761 recursively_expand() to recursively_expand_for_file() and provide
3762 an extra argument, struct file. If the argument is provided, set
3763 the variable scope to that of the file before expanding.
3764 * variable.h (recursively_expand): Make this a macro that invokes
3765 recursively_expand_for_file() with a NULL file pointer.
3766 * variable.c (target_environment): Call the renamed function and
3767 provide the current file context.
3768 Fixes Debian bug #144306.
3770 2002-04-28 Paul D. Smith <psmith@gnu.org>
3772 Allow $(call ...) user-defined variables to be self-referencing
3773 without throwing an error. Allows implementation of transitive
3774 closures, among other possibly useful things.
3775 Requested by: Philip Guenther <guenther@sendmail.com>
3777 * variable.h (struct variable): Add a new field: exp_count, and
3778 new macros to hold its size and maximum value.
3779 (warn_undefined): Make this a macro.
3780 * variable.c (define_variable_in_set): Initialize it.
3781 * expand.c (recursively_expand): If we detect recursive expansion
3782 of a variable, check the exp_count field. If it's greater than 0
3783 allow the recursion and decrement the count.
3784 (warn_undefined): Remove this (now a macro in variable.h).
3785 * function.c (func_call): Before we expand the user-defined
3786 function, modify its exp_count field to contain the maximum
3787 number of recursive calls we'll allow. After the call, reset it
3790 2002-04-21 Paul D. Smith <psmith@gnu.org>
3792 Modified to use latest autoconf (2.53), automake (1.6.1), and
3793 gettext (0.11.1). We're using gettext's new "external" support,
3794 to avoid including libintl source with GNU make.
3796 * README.cvs: New file. Explain how to build GNU make from CVS.
3798 * configure.in: Modify checking for the system glob library.
3799 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3800 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3801 etc. will manage it correctly). Set an automake conditional
3802 USE_LOCAL_GLOB to decide whether to compile the glob library.
3804 * getloadavg.c (main): Include make.h in the "TEST" program to
3807 * Makefile.am: Remove special rules for loadavg. Replace them
3808 with Automake capabilities for building extra programs.
3810 * signame.c: This file does nothing if the system provide
3811 strsignal(). If not, it implements strsignal(). If the system
3812 doesn't define sys_siglist, then we make our own; otherwise we use
3814 * signame.h: Removed.
3816 * main.c (main): No need to invoke signame_init(). Update copyright.
3818 * ABOUT-NLS: Removed.
3819 * gettext.c: Removed.
3820 * gettext.h: Get a simplified copy from the gettext package.
3822 * i18n/*.po: Moved to po/.
3825 * config/*: Created. Contains package configuration helper files.
3826 * config.guess, config.sub: Moved to config directory.
3828 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3829 Rework to use new-style autoconf features. Use the "external"
3830 mode for gettext. Make the build.sh config file conditional on
3831 whether build.sh.in exists, to avoid autoconf errors.
3832 * acinclude.m4: Removed almost all macros as being obsolete.
3833 Rewrote remaining macros to use AC_DEFINE.
3834 * acconfig.h: Removed.
3836 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3837 conditional to handle customs support. Remove special handling
3840 2002-04-20 Paul D. Smith <psmith@gnu.org>
3842 * function.c (func_call): Don't mark the argument variables $1,
3843 etc. as recursive. They've already been fully expanded so
3844 there's no need to do it again, and doing so strips escaped $'s.
3845 Reported by Sebastian Glita <glseba@yahoo.com>.
3847 * remake.c (notice_finished_file): Walk through double-colon
3848 entries via the prev field, not the next field!
3849 Reported by Greg McGary <greg@mcgary.org>.
3851 * main.c (main): If the user specifies -q and asks for a specific
3852 target which is a makefile, we got an assert. In that case it
3853 turns out we should continue normally instead.
3855 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3857 * i18n/he.po: Installed a new translation.
3859 2002-01-07 Paul D. Smith <psmith@gnu.org>
3861 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3863 2001-12-04 Paul D. Smith <psmith@gnu.org>
3865 * i18n/ja.po: Installed an updated translation.
3867 2001-09-06 Paul Eggert <eggert@twinsun.com>
3869 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3870 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3872 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3874 (main): Get rid of any avoidable limit on stack size.
3876 2001-09-04 Paul D. Smith <psmith@gnu.org>
3878 * i18n/da.po: Installed an updated translation.
3880 2001-08-03 Paul D. Smith <psmith@gnu.org>
3882 * i18n/fr.po: Installed an updated translation.
3883 Resolves Debian bug #106720.
3885 2001-06-13 Paul D. Smith <psmith@gnu.org>
3887 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3890 2001-06-11 Paul D. Smith <psmith@gnu.org>
3892 * i18n/ko.po: Installed a new translation.
3894 2001-05-06 Paul D. Smith <psmith@gnu.org>
3896 Modify the EINTR handling.
3898 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3899 the way in which we manage the file descriptor/signal handler race
3900 trap to be more efficient.
3902 2001-05-06 Paul Eggert <eggert@twinsun.com>
3904 Restart almost all system calls that are interrupted, instead
3905 of worrying about EINTR. The lone exception is the read() for
3908 * configure.in (HAVE_SA_RESTART): New macro.
3909 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3910 * main.c (main): Use SA_RESTART instead of the old,
3911 nonstandard SA_INTERRUPT.
3913 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3914 * main.c (bsd_signal): New function or macro,
3915 if the implementation doesn't supply it.
3916 (The bsd_signal function will be in POSIX 1003.1-200x.)
3917 (HANDLESIG): Remove.
3918 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3920 * make.h (EINTR_SET): Remove.
3921 (SA_RESTART): New macro.
3923 * arscan.c (ar_member_touch): Don't worry about EINTR.
3924 * function.c (func_shell): Likewise.
3925 * job.c (reap_children, free_child, new_job): Likewise.
3926 * main.c (main): Likewise.
3927 * remake.c (touch_file, name_mtime): Likewise.
3929 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3930 if fstat failed with errno!=EINTR, the error was ignored.
3932 * job.c (set_child_handler_action_flags): New function.
3933 (new_job): Use it to temporarily clear the SIGCHLD action flags
3934 while reading the token.
3936 2001-05-02 Paul D. Smith <psmith@gnu.org>
3938 * job.c (start_job_command): Don't add define/endef per-line flags
3939 to the top-level flags setting.
3941 2001-04-03 Paul D. Smith <psmith@gnu.org>
3943 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3944 bit on error, so check for odd return values, not non-0 return
3946 (VMS_get_member_info): Calculate the timezone differences correctly.
3947 Reported by John Fowler <jfowler@nyx.net>.
3950 2001-03-14 Paul D. Smith <psmith@gnu.org>
3952 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3953 value before invoking define_variable().
3954 Reported by John Fowler <jfowler@nyx.net>.
3956 2001-02-07 Paul D. Smith <psmith@gnu.org>
3958 * read.c (record_target_var): If we reset the variable due to a
3959 command-line variable setting overriding it, turn off the "append"
3962 2001-01-17 Paul D. Smith <psmith@gnu.org>
3964 * variable.c (lookup_variable) [VMS]: When getting values from the
3965 environment, allocate enough space for the _value_ plus escapes,
3966 not enough space for the name plus escapes :-/.
3967 Reported by John Fowler <jfowler@nyx.net>.
3969 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3970 warnings that make generates, so it doesn't look like an error.
3971 Reported by Karl Berry <karl@gnu.org>.
3974 Fix for PR/2020: Rework appended target-specific variables. I'm
3975 fairly confident this algorithm is finally correct.
3977 * expand.c (allocated_variable_append): Rewrite. Instead of
3978 expanding each appended variable then adding all the expanded
3979 strings together, we append all the unexpanded values going up
3980 through the variable set contexts, then expand the final result.
3981 This behaves just like non-target-specific appended variable
3982 values, while the old way didn't in various corner cases.
3983 (variable_append): New function: recursively append the unexpanded
3984 value of a variable, walking from the outermost variable scope to
3986 * variable.c (lookup_variable): Remove the code that looked up the
3987 variable set list if the found variable was "append". We don't
3989 (lookup_variable_in_set): Make this non-static so we can use it
3991 (try_variable_definition): Use lookup_variable_in_set() rather
3992 than faking out current_variable_set_list by hand (cleanup).
3993 * variable.h: Add a prototype for the now non-static
3994 lookup_variable_in_set().
3996 2000-11-17 Paul D. Smith <psmith@gnu.org>
3998 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
3999 WINDOWS32 port to assume timestamps can be up to 3 seconds away
4000 before throwing a fit.
4002 2000-11-17 Paul D. Smith <psmith@gnu.org>
4004 * read.c (readline): CRLF calculations had a hole, if you hit the
4005 buffer grow scenario just right. Reworked the algorithm to avoid
4006 the need for len or lastlen at all. Problem description with
4007 sample code chages provided by Chris Faylor <cgf@redhat.com>.
4009 2000-10-24 Paul D. Smith <psmith@gnu.org>
4011 * gettext.c (SWAP): Declare this with the prototype, otherwise
4012 some systems don't work (non-32-bit? Reported for Cray T3E).
4013 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
4015 2000-10-05 Paul D. Smith <psmith@gnu.org>
4017 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
4018 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4020 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4022 2000-09-22 Paul D. Smith <psmith@gnu.org>
4024 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4025 parts of the real gettext.h here, and we expect to really include
4026 the real gettext.h later. If we keep this #define, it's ignored.
4028 2000-09-21 Paul D. Smith <psmith@gnu.org>
4030 * main.c (log_working_directory): Rework the text to use complete
4031 sentences, to make life simpler for the translators.
4033 2000-08-29 Paul D. Smith <psmith@gnu.org>
4035 * file.c (remove_intermediates): Print a debug message before we
4036 remove intermediate files, so the user (if she uses -d) knows
4039 2000-08-21 Paul D. Smith <psmith@gnu.org>
4041 * variable.c (try_variable_definition): Change how we handle
4042 target-specific append variable defns: instead of just setting the
4043 value, expand it as an append _but_ only within the current
4044 target's context. Otherwise we lose all but the last value if the
4045 variable is appended more than once within the current target
4046 context. Fixes PR/1831.
4048 2000-08-16 Paul D. Smith <psmith@gnu.org>
4050 * function.c (func_shell): Nul-terminate the buffer before
4051 printing an exec error message (just in case it's not!).
4052 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4054 2000-07-25 Paul D. Smith <psmith@gnu.org>
4056 * job.c (construct_command_argv_internal): Add "~" to the list of
4057 sh_chars[] which disallow optimizing out the shell call.
4059 2000-07-23 Paul Eggert <eggert@twinsun.com>
4061 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4062 supersedes --disable-nsec-timestamps.
4063 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4064 * README: Remove --disable-nsec-timestamps.
4066 * filedef.h (struct file.low_resolution_time): New member.
4067 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4068 * remake.c (update_file_1):
4069 Avoid spurious rebuilds due to low resolution time stamps,
4070 generalizing the earlier code that applied only to archive members.
4071 (f_mtime): Archive members always have low resolution time stamps.
4073 * configure.in: Remove --disable-nsec-timestamps, as this has
4074 been superseded by .LOW_RESOLUTION_TIME.
4076 2000-07-23 Paul Eggert <eggert@twinsun.com>
4078 * configure.in (enable_nsec_timestamps): Renamed from
4079 make_cv_nsec_timestamps, since enable/disable options
4080 shouldn't be cached.
4082 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4083 and Paul Eggert <eggert@twinsun.com>
4085 * file.c (file_timestamp_now):
4086 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4087 so that clock_gettime is not linked unless needed.
4089 * filedef.h (FILE_TIMESTAMP_HI_RES):
4090 Remove definition; "configure" now does this.
4092 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4093 to before high resolution file timestamp check,
4094 since that check now uses uintmax_t.
4095 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4096 high resolution file timestamps.
4097 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4098 so that we don't link in clock_gettime unnecessarily.
4100 2000-07-17 Paul D. Smith <psmith@gnu.org>
4102 * i18n/ja.po: New version of the translation file.
4104 2000-07-07 Paul D. Smith <psmith@gnu.org>
4106 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4107 the offset calculation.
4108 (name_mtime): Replace EINTR test with EINTR_SET macro.
4110 2000-07-07 Paul Eggert <eggert@twinsun.com>
4114 * remake.c (update_file_1):
4115 Avoid spurious rebuilds of archive members due to their
4116 timestamp resolution being only one second.
4117 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4118 the clock's resolution being lower than file timestamps'.
4119 When warning about future timestamps, report only the discrepancy,
4120 not the absolute value of the timestamp and the current time.
4122 * file.c (file_timestamp_now): New arg RESOLUTION.
4123 * filedef.h (file_timestamp_now): Likewise.
4124 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4126 2000-07-05 Paul D. Smith <psmith@gnu.org>
4128 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4129 to listp. Fixes PR/1793.
4131 2000-06-26 Paul Eggert <eggert@twinsun.com>
4133 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4135 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4137 * remake.c (f_mtime): Remove unused var memtime.
4139 2000-06-25 Martin Buchholz <martin@xemacs.org>
4141 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4142 Ran spell-check on make.texinfo.
4144 2000-06-23 Paul D. Smith <psmith@gnu.org>
4146 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4147 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4148 * make.h: Define these macros.
4150 * Version 3.79.1 released.
4152 * configure.in: Add a new option, --disable-nsec-timestamps, to
4153 avoid using sub-second timestamps on systems that support it. It
